Is anyone else running this cab file??
Before loading it, I pulled it apart with a cab editor to see what it was. I was very excited to see that it uncovered the radio band selction capabilities, so I quickly installed it.
But this where things got funny. I refuses to give me the option for the for GSM 1900, although it is clearly called out in the registry edits the cab lays down. I am running the 1.13 radio, with system 1.40.00, and was wonder if anyone else can verify this as a problem? I am wondering if this is a software issue in either the cab, system, or radio... Or to my horror is the SX66 retarded to triband???

Ok, looks like TheLastOne answered my question in another post. Funny that the site search failed to turn this up:
1) Phone Band Selection: BandSel_BAWWE_140921.sa.CAB
- I've played with this a bit, their cab is actually ****ed up, as they have tried to get 6 selections onto the page when only 5 are possible. Through the registry you can have any band configuration you want selectable. I personally LOVE this feature.
GSM 1900 is the 6th selection, hence it doesn't show up. But this now leaves a glaring question, what are ALL the selectable options? I note the 900/1800 option with a value of 3, but is there a 850/1900 option(This would be prefect when I go to aruba), and what is that value??
GSM900 has a value of 1
GSM1800 has a value of 2
GSM900/1800 has a value of 3
GSM1900 has a value of 4
Automatic has a value of 7
gsm850 has a value of 8
So, what are values 5 and 6?? I could set those values, but I have no idea how I'd check to see what band I am current using. Anyone got any thoughts?
-Chris
Either 5 or 6 is 850/1900, from my tests, but I forget which.
If you don't mind, how did you determine that?
-Chris
In my location, I have access to two GSM networks, one which is exclusively 1900 and the other is 850. Set to either 5 or 6, I could get on both. (So I'm not positive it's EXCLUSIVELY 1900 and 850, since there is no 900 or 1800 here to test).
I did this a bit ago, so I don't properly remember.
The value is a bitmask:
bit 1: 900
bit 2: 1800
bit 3: 1900
bit 4: 850
so 5 means 101b - 1900+900
6 means 110b - 1900+1800
Setting 7 would make GSM to use 900, 1800, 1900
Probably the GSM part also tries to register on 850Mhz when 1900 is selected.
Mamaich,
You rock. You never cease to amaze me. Very cool, thanks.

Can you post a link to this CAB file?
Modified Band Select CAB for USA
I modified the CAB for USA only 850, 1900 and Auto
I ran the updated CAB file you posted here, seems to be working ok, although signal strength (on the new bands) seems to be weaker than what I had before installing the cab. I am wondering, is there ever away to revert back to the original band options or settings ?
I am wondering the same thing, because NONE of the 3 options i had available to me when I installed this (Auto, GSM 850/1900 (NA), GSM 900/1800(Euro/Asia) were selected.
When I selected Auto, I began ROAMING, and I'm not certain why. The only way I know of to return this back to factory state is to hard reset.
Does anyone have THE ORIGINAL CAB, before the mods were made so that ALL options were available?? I'd really like to have that cab so that I can see what option my PDA2k on Cingular was using...
Here is the original CAB file, it did not work on my SX66 (see the first few posts on this thread) so I modified it to use only 850/1900 and Auto. I have had no problems with the modified CAB. Signal strength has not been degraded.
thanks, Cruzzer.
the modified CAB put me into permanent ROAM no matter what frequency I chose (or killed the phone entirely because there wasn't a 900/1800 tower).
I managed to get a hold of Chris and he helped me make some registry mods that gave me the original functionality back.
Interestingly enough, I had to put the phone thru a couple of different SR's before it would stop roaming, even after switching back to JUST 850.
Goofy, huh?
Care to go over the registry edit you made? Thanks.
Question
First of all, thans for the Band Select created by Cruzzer for US users. After I install his band select, it's the first time that I can use my phone in my office located in a basement. But I have a problem. In his band select, there are three options, automatic, GSM 850, and GSM 1900. When I selected automatic, my phone couldn't find the network. But when I selected GSM 850, it works perfectly. At first, I understand that by selecting my phone to automatic, my phone should search both GSM 850 and GSM 1900. But I don't know why it always show no network. Did I do anything wrong?
By the way, my phone is O2 XDA IIs brought from Thailand. (O2 Asia)
I believe that there is a bug in BA when working with GSM850.
In fact, automatic should search between GSM850, 900, 1800 and 1900.
Usually when using "automatic" where GSM850 networks exists, makes BA not being able to find any network.
Are you using WM2003SE ?
JP
Yep WM2003SE
Yes, I'm using WM2003SE.
I also tried another band select created by one of our members in http://forum.xda-developers.com/showthread.php?t=297099 His band select gives four options:
1. automatic
2. GSM 850/GSM 1900 (north america)
3. GSM 900/GSM 1800 (Europe)
4. Reset Values to Zero
When I selected GSM 850/GSM 1900 (north america), my phone had no signal. So, right now I have to go back to BandSel_BAWWE_140921.sa.us and manually select GSM 850.
Yes, unfortunely, that seems to confirm my teory.
If it works for you at 850, keep at that. Just remember that if you upgrade to WM6, band selection will not be available and it will be locked to your choice done in WM2003, in this case 850.
Your BA, will no longer be quad-band (the same as mine).
JP
Too bad
Thanks for confirming the bug in BA. Too bad. I want to upgrade to WM6 but I know there is no way to select which band in WM6. So...I'm stuck with WM2003SE. I wonder, can we edit the registry to manually select the GSM band in WM6?
I've tryed and some other did also, but it seems that both the .cab and also registry tweaks for band selection do not work on WM6.
It does not mean that you will have a problem with WM6, but rather that the band that you have selected on WM2003 will remain "locked" when using WM6 and cannot be changed.
In my case, i'm using the 900/1800 band selection and it works just fine with WM6 (i've used Helmi's and now i'm using Xplode's) but i cannot select 850 for example.

Has any been able to get 3G to work in the USA yet?
thank you,
jdm
I would say that it is imminent that the US version of the S730 will be released soon. AT&T or T-Mobile may pick it up (T-Mobile's 3G network in NYC just went live, but there are no phones). If so, I would suspect that some of these crafty folks (like Alcaline) would be able to extract the radio ROM, and make it available for the S730 that we all have (the european version).
But, here's the most important part... It all depends on whether or not the European version of the S730 has the radio chipsets that will support 3G on the frequencies that are 3G in the US. There is no known answer "available" to this, so it can only be discovered by testing.
The current S730 uses the 2100 band for 3G speeds and ATT is deploying 3g on 1900 and 850 I believe and they sell a decent ammount of 3g phones. T-Mobile is working on setting one up on the 1700/2100 band but I dont care for T-Mobile.
I have watched my phone at times flip into 3G mode for a few minutes then revert back to Edge, its trying but cant work properly without the right frequencies.
Check out the chipset datasheet. Bottom of page three explains the specific radio chipset combos and their support for different freqs.
I suppose, to save on manufacturing costs, they could have used the single chipset that supports 3G on all freqs (RTR 6285), but I believe this is unlikely due to the difference in model number that was submitted to the FCC (European version: WING220, US version: WING200).
Who knows though.
3G in US
Hermes models had different model #'s HERM100, HERM200 and had the same radios, in some cases minor difference such as case style, i.e removal of video calling camera etc. With any luck we have the RFR6500 + RTR6275 Combo, or as you mentioned the RTR6285 and just not a radio rom that allows 1900+850 3G. I was looking on the FCC site and they have some interesting screen shots, one of which shows one(s730) with what appears to be the front camera covered up and another which shows a radio rom(R 0.27.03.05B), one that, to do the tests would likely need to support 1900+850. Check Page 250 / 11 in the PDF. However, also in the test is the lack of any mention of 2100 Mhz test, which would suggest that either the US 3G Radio won't support 2100Mhz or that it indeed has different hardware that won't support 2100Mhz. At any rate it would be interesting to know if anyone has tried to flash one of the pre-prod roms for the wing 200 onto the wing220 and see if they are able to connect up to 1900+850 3G.
http://gullfoss2.fcc.gov/prod/oet/forms/blobs/retrieve.cgi?attachment_id=890469&native_or_pdf=pdf
I suppose only time will tell.
Wow... nice investigative work. Very interesting. I'll start hunting around for the ROM.
[edit]
Searched google and, my favorite, napalm with no luck. I wonder if we can lure an FCC testing engineer into the XDA-dev realm. muahahaha
I was searching some of the other posts, and it appears that most of the pre-prod radio rom testing had been focused on GPS functionality. Has anyone been able to throw on any of the pre-prod radios with an ATT SIM and tested to see if it can connect to WCDMA -> US Band (1900+850) ??
I have no possibility to check the 3G in the USA from my location in Norway.
But just to get this clear, because I have changed my Radio more often then most people change their underweare.
Is everybody able to select WCDMA and then US Band in the settings?
I dont know if this is selectable on all devices or if this is made available after my radio flahings.
I believe all S730's have the following options available.
Network Type:
Auto
GSM
WCDMA
Band Type:
Auto
US Band
Euro Band
Japan Band
For it to actually be able to operate on all of these frequencies I believe it would need to use the the RTR6285 chipset as the other 2 combos would not support all of the different frequencies combinations.
US Band -> GSM 850+1900 / UMTS 850+1900 (ATT)
Euro Band -> GSM 900+1800 / UMTS 2100
Japan Band -> UMTS 2100+800 (not positive on this one)
If I change band to from Auto -> WCDMA I do not get an error but no 3G Icon and all calls fail. If I then go and change to US Band while having WCDMA selected it indicates that it cannot change to that GSM/UMTS Band. Also interesting, If I stay on WCDMA and select Euro Band, no error, but of course all calls fail. I then tried to change to Japan Band, no error and no phone calls. Finally I am still on WCDMA and I switch to US Band and I get the error that indicates I cannot change to that band. So, I would be interested to know Alcaline if you see the same behavior on some of the other radios you have been trying to see they allow the switch to WCDMA / US Band combo.
Thanks
Can anyone else confirm this behavior on any of the other Radios out there?

I have the ability to tell my phone I am in the states, but it does nothing (default settings though)
Was the US version (WING200) of this phone ever released? Or has anyone gotten the EU version to work on any US 3G networks? Wondering about T-Mobile...
I understand that currently the Diamond does not support 3g data in the USA. There are rumors that the Diamond will eventually release in the US on the GSM network sometime after the CDMA release. Seeing as HTC already proved that sometimes they can enable frequencies with just a radio rom update, do you think the current Diamond will someday be able to support 3g in the USA?
I sold my Tilt a few weeks ago and got myself an Iphone. I am starting to hate the Iphone and really would like to go back to a WM device. But the Tilt is not an option and the only phone that looks worth the jump is the Diamond. But I do not want to buy a phone that will never be able to support 3g. Edge is just too slow, and with AT&T you pay the same data rate for an Edge or a 3G phone.
I have done plenty of searches and can't seem to find any conclusive answers. Maybe there isn't one.
Thanks for any suggestions you may have. Please don't turn this into an iphone bashing thread. The iphone has many good qualities, it just does not suit my needs as I thought it would.
Jeff
no you must wait for the local diamond release. they are hardware specific.
Well that just sucks. I guess I will have no choice but to wait for the Diamond or the Xperia to invade our borders.
its does suck, i have a Diamond from Asia and i cant use the 850Mhz 3G Telstra network.... lucky for the 3Telstra joint venture network!
I thought that was one of the benefits of the new 1.93 ROM, it utilizes 850Mhz, no?
Mark
thats only GMS band and is also only sim card specific. i have the 1.93 rom and a telstra next g sim and i only get UMTS (900-2100) + GSM (900+1800) bands...

Thats just a bummer. Guess it's edge for me, unless something miraculously happens
Can anyone explain exactly what it will take for HSDPA in the US?
Hi -
Similar to the original poster, I have been watching with anticipation the development of the Diamond and the XDA cookers' work on unlocking its capabilites. I too am confused, with many conflicting posts about the ability to do HSPDA in the US. Can anyone explain exactly what it will take? Based on my understanding:
1.) Ability to transmit and recieve on the radio frequency used by the telco / phone company for UMTS service (Universal Mobile Telecommunications System). For AT&T, I thought this frequency was 850 mhz. Based on peoples' reports and some testing done, it seems like the Diamond can be unlocked through a ROM flash to broadcast and recieve on 850 mhz. So far, so good.
2.) Ability to use the UMTS service
My reading of Wikipedia seems to say that UMTS is a "technology" -
This is different from a "standard" like GSM,which is an integrated system of hardware (radio transmitters and towers), an "air interface" (a set of protocols to handle packet transfers, analogous to TCP/IP on the Internet, only using radio waves rather than wires), an "infrastructure" (base station sub-system and GPRS (packet) subsystem - towers and the computers and routers that connect them) and connection software (validating users, tracking usage, billing, transmission control codecs, etc.). UMTS is a collection of transmission control codecs and user identification codecs operating within a GSM network. So, UMTS is a phrase that describes improvements to the old, 2G GSM protocols. But it is still GSM.
AT&T in the US is using WCDMA as the "air interface" over which it is running its UMTS service. It is using the 850 mhz frequency. One key difference between GSM and UMTS is that UMTS uses a "Universal Subscriber Identification Modue" (USIM) rather than a plain old Subscriber Identificaton modue (SIM). If AT&T's UMTS service requires a USIM, then having only a SIM will prevent you from accessing the UMTS service - you will only be able to access the data service offered by the GSM, which is EDGE in the US, not WCDMA (i.e., only 2G). This is regardless of hardware. If this is the case, then it's a bummer.
HOWEVER....the UMTS service CAN use SIM cards as well, so AT&T may have theirs configured to use SIM cards as well. I currently have the HTC Trinity with what I think is a SIM card - I was forced to "upgrade" the SIM card when Cingular "integrated" with AT&T, so my card is branded Cingular, but has the snazzy 3G fireball on it. So maybe it's actually a USIM? My Trinity does have the "H" icon show up, and I can get 300kbps or so tethering to my laptop (but not above that - grrrr...) so maybe I'm getting UMTS service on that device? If so, then the SIM vs USIM should not be an issue if I got a Diamond.
3.) Ability to use the HSPDA protocol
As far as I can tell, HSPDA is pure protocol - just like TCP/IP. It achieves faster speeds by using fast packet scheduling and something called adaptive modualtion and coding. It is part of the UMTS standards, so it's actually part fo the overall UMTS system, but not everyone uses it. If your phone and your carrier can use this protocol, you can get HSPDA.
Based on the above, it seems reasonable that the Diamond is capable of transmitting at HSPDA speeds in the US on AT&T's network. Has anyone been able to actually do this? If not, could those much more informed than me explain the obstacle? Is it a setting on AT&T's side? A setting on the Diamond? Is the radio hardware for UMTS somehow different? Does the Diamond lack WCDMA capability due to lack of software?
I understand that some people have tried selecting the band on their ROM-flashed phone to get 3G on AT&T with no success, but that doesn't mean it can't be done. I'm trying to understand the eaxt nature of the obstacle.
Thanks!!!
Mike
I can't speak for all the technical hardware specs possibilities. But here's the latest status as i understand it:
1. There are at least 2 GSM-based Diamond versions available now: DIAM100 and DIAM130. The DIAM100 is the original one that went on sale. The DIAM130 seems to be the new Telstra Diamond that does support 850 3G.
2. There are lots of radio ROMs out available now. Some unlock 850 GSM for the DIAM100, which was previously thought impossible due to lacking of an 850 radio antenna. But that was a lie obviously. No Radio ROMs are currently avail that have successfully unlocked 850 3G. And since the DIAM130 is the only one working on 850 3G (using a radio ROM that is available for the DIAM100 even), the prevailing thought is it is actually a HW limitation on the DIAM100. I.e. it cannot do 850 3G no matter the radio ROM. (Note that OS ROMs have no effect on the radios ability. However, they might unlock the availability of the frequency selection in the Phone Settings window on WM. Note also that simply the existence of a selection in that window does NOT mean it physically can do that frequency.
3. No radio ROM thus far has made any iteration of the Diamond capable of doing 1700 anything, which is what TMo US would need for its 3G network. So, if a TMo US one is to become available, it would be yet another HW version.
#2 and #3 are still just theory, but pretty solid ones at this point.
So, my question is re: the DIAM130. What other 3G bands is it capable of. Only 850? Is it still quad-band GSM capable? If its flashed with other Radio ROMs, does it still maintain the same capabilities? I'd consider getting one if possible and using it here on AT&T if it is (or can be) quad band GSM and 850 3G. Esp if it still had 2100 3G, or even if it could be flashed when necessary to support 2100 3G when I travel. The lengths I've considered going to for this.
In any case, I lose more and more interest in this product each day. I'm inching closer to a hopeful AT&T Omnia, which too has drama surrounding it. And since I just got my g/f an iPhone 3G, I hate to admit, I'm heavily considering one as well now. What I might lose in flexibility, I think I would gain in having a solid device, that works worldwide 3G, and would keep everything I want in sync.
Sad really. I've been a WM-trooper for a decade now. 80% my music is in WMA format. For the stupidity of these dramas, WM may very well lose a devotee. (And as you can see from my willingness to import the phone and flash it whenever necessary, I'm not just giving up, I'm trying my best. but when the companies make it this hard, you gotta question if its worth it.)
Thanks Jomo!!!
Sounds like we're in the same boat. I won't get an iPone because part of my reason for having the phone is being able to tether to my laptop in an emergency. If the Diamond can't do it, I'll stick with my Trinity, which can. Really, I just want the better form factor...
One thing that has me confused is the whole radio thing. I'm no electrical engineer, but it seems like there are two components to the "radio" of the cellphone.
1.) The hardware - specific physical characteristics like the length of the antenna will determine the frequency you can use. I remember the old days of citizens band radios (that's CBs to those good buddies who saw Convoy <grin>) where you had to change physical crystals to get the right frequencies. Yes, apparently I'm old (geez, when did THAT happen???). I can also see the clock cycle of the radio's DSP determining how quickly the radio can handle packets.
2.) The software - herein lies all the nitty gritty details about protocols and the like - you need to have radio software that uses all of the hardware - like "turning on" the 850 band.
I guess the real questions for you gurus out there are
a.) how much of the UMTS protocol is programmed into the chip versus based on software (more software-based would support there being a software solution)? The chip used in the Diamonds is the Qualcomm 7201 chipset (at least the GSM ones do) which specifically lists UMTS as a capability, so it seems like the software just isn't using it right.
b.) do you need hardware components for each frequency of UMTS?
It just seems that going from GSM to UMTS is a matter of using different software, although you would have to have hardware capable of UMTS speeds. Ifthis is the case, then a hardware solution is possible. If it requires sepcial software to add into the existing software, we may be out of luck until one is created with the right stuff.
Ugh. My head hurts. Learning cellular radio through internet research is not easy. I suppose it would be easier if I were smarter <grin>
Mike
This may be old news, and still doesn't answer the querstion whether the current batch of Diamonds can be software / ROM updated to do US 3G, but at least there is a device that can - the product name DIAM110 (as opposed to the DIAM100 and DIAM130) has been submitted to the FCC a while back and definitely does do 850 UMTS.

Excellent thread!
Very informative - thanks for doing the research and putting it all in one place! I too am somewhat confused as to the availability of 3G data access on AT&T - this thread has helped me understand some of the technologies involved and raised some interesting questions.
3.5G is backwards compatible with 3G
I just read in the wikipedia that 3.5g is backwards compatible with 3G tecnology, so i cant find the point in which Diamonds just CANT use regular 850 3G. Perhaps is just a little tweaking over the HW. But I believe it will be done sooner or later
DIAM100 with RTR6285?
Thanks for the informative post. I've been looking for the answer to this question long before I got my diamond. Here's what I've found so far. Hope it helps.
According to this page and this page, Diamond uses Qualcomm RTR6285 as its RF Transceiver. And based on the press release from Qualcomm,
The RTR6285 transceiver supports the following bands:
* North American triple-band UMTS (bands 2, 4, 5)
* Japanese triple-band UMTS (bands 1, 6, 9)
* European, Chinese and rest-of-world triple-band UMTS (bands 1, 3, 8)
* Global quadruple-band GSM and EDGE (800/900/1800/1900 MHz)
Note that "North American triple-band UMTS (bands 2, 4, 5)" means it supports 1900MHz, 1700MHz, and 850MHz
Here's the wiki page that lists the UMTS frequency bands
Many users on this forum mentioned that Diamond lacks 850MHz 3G support due to the hardware limitation, but that contradicts the RTR6285 press release. Can somebody please confirm that DIAM100 uses RTR6285?
Thanks,
Bruce
WOW!!! bruce0126 you just make my day!!!
Keep the dream alive people!
So if its the same Hardware then what is keeping the phone from working on UMTS 850 band?
The ROM is activated for the North American frequencies so its not a ROM issue.
Thats ODDDDDDD
could it be lack of antenna for those specific bands?
we need a techwiz!!
Ive seen the specs also and the radio hardware is supposed to recieve at 850mhz, perhaps the transmited has been " Programmed" in factory to forbid the use of this particular band. Of course im only guessing.
Any one has a good new about american 3G in our DIAM100 ??

TD Japanese Version couldn't use the WCDMA(2100) Network in China.
This TD seemed to use WCDMA 1700 in Japan, but couldn't be used in China. I've tried flashing a few Roms, also some Radios. Still it didn't.
Is this TD only support 1700MHz in Japan, which means it couldn't be used in WCDMA Network in China, which is 2100MHz?
Sorry for my poor translation.

The translation is better then the kanji. {I can't remember Katakana or Hirogana, been too long since I have read, wrote, or even spoke} If you can translate this back for Shishi, that would be wonderful. Thanx for the help as a translater.
Check the model # {label under battery}, & enter the model into the search engine @ PDADB.net. This will list all the frequencies your specific model is capable of. Model # will be DIAM*** {replace the *s with the #s on your Diam.}
You can flash ROMs until the chip burns out, but this will not help, because all the frequency data is in the Radio. If the site says that your model is capable of 2100 {which I believe it should be}, then just find a radio that runs at 2100MHz, & flash it.
If this is a CDMA model then I am not too sure what the frequencies are. GSM Touch Diamonds are quad-band phones & definately utilize the 2100MHz WCDMA. Soe GSM Diams only show the tri-band frequencies, but if you just flash a quand-band Radio to it, & it'll be fully functional as a quad. It has the Hardware, you just may need to change the software.
Also, if you go to the phone settings, there is a tab for "Band". Look there & see if the 2100MHz is listed. If it is, check that it's enabled. If it's not then just flash a quad radio.
Good luck

Check the model # {label under battery}, & enter the model into the search engine @ PDADB.net. This will list all the frequencies your specific model is capable of. Model # will be DIAM*** {replace the *s with the #s on your Diam.}
You can flash ROMs until the chip burns out, but this will not help, because all the frequency data is in the Radio. If the site says that your model is capable of 2100 {which I believe it should be}, then just find a radio that runs at 2100MHz, & flash it.
If this is a CDMA model then I am not too sure what the frequencies are. GSM Touch Diamonds are quad-band phones & definately utilize the 2100MHz WCDMA. Soe GSM Diams only show the tri-band frequencies, but if you just flash a quand-band Radio to it, & it'll be fully functional as a quad. It has the Hardware, you just may need to change the software.
Also, if you go to the phone settings, there is a tab for "Band". Look there & see if the 2100MHz is listed. If it is, check that it's enabled. If it's not then just flash a quad radio.
Good luck

检查你的TD的型号（取下电池你就能看到），将你的手机型号输入PDADB.net的搜索引擎，它将会列出你的型号所适合的频率。型号是DIAM***。
你可以刷ROM，但是这没有作用，因为所有和你频率相关信息都在Radio里面。如果你的型号适合2100Mhz，那就选择一个2100频率的Radio，再刷Radio。
如果这个TD是CDMA型号的，那么我也不清楚他能适合频段是多少Mhz。GSM的TD是4频手机，所以口肯定能使用WCDMA的2100Mhz。GSM只显示3频，但如果你刷了四频的Radio，它就是个全功能的4频手机了。你只需选用合适的软件来激活它的硬件。
此外，如果你进入手机的设置项，其中有一个频段(BAND)选项，看看是否其中有2100Mhz 的频段，如果有，只需启用即可，如果没有，则需要刷一个4频段的Radio

Hello everyone,
I bought a G1 from Rogers in canada, but now I live in germany.
I don't know how it actually works, but I have been unable to get 3G connections here (only GPRS and normal cell phone), using the O2 company. After doing some research I realized that the radio frequencies are different (according to http://www.gsmarena.com/network-bands.php3?sCountry=GERMANY, then go to canada to check it out).
Are there any possibilities to change the radio frequencies of UMTS? My phone is rooted.
Thanks a lot!
Dial:
*#*#4636#*#*
Then goto phone info
Scrool down list
Change preffered network to WCDMA only for 3G only
Exit
Edit: O2 doesnt use the same 3G freq as Rogers, so you must stay with EDGE.
if memory serves correctly - o2 and tmobile work on the same frequencies in germany
if this is the case there is nothing you can do as the radio frequency is a hardware thing
Thanks for the reply!
I did that, but after a while it changes back to 'WCDMA preferred'.
I went to the O2 store, and the guy tested the chip with a Palm Pre, and it worked fine.. but with my G1 it didn't, only GPRS.
rogers use different frequencies to most other providers worldwide
rogers, atnt and some south african one use one set for 3G but everyone else uses another
you WILL NOT get 3G on the rogers dream on frequencies not used by rogers
also

will this work with any phone? Sorry NTT. i have just bought a htc touch 3g but it won't work in the bush. the phone supports HSDPA/WCDMA:
900/2100 MHz and out here we have 850/2100 mhz wcdma.

All I know is that it allows you to force a specific phone freq, im not sure if all HTC phones have test mode which that number brings up. It doesnt allow you to change the freq only force one type. So a quad-band phone can be forced to use 2G only instead of 3G.It doesnt give access to unsupported bands cause thats a hardware thing.
I am discussing this very subject here: http://forum.xda-developers.com/showthread.php?p=15461093&posted=1#post15461093 would appreciate any comments or suggestions.
