OK guys it might sound stupid but it really concerns me, we all know HD7 supports speeds upto 14.2Mbps download right.
I have a unlocked TMOUS branded HD7, while I know TMOUS is on AWS1700/2100 blah blah, even though the device itself has retained the UMTS 2100 apart of having the 1700/2100 AWS bands.HD7 has HSDPA speeds on AWS, now my question is does it have that on the UMTS 2100???
Where I live we have UMTS 2100, the phone gets the 3G network everything, cuz if it did not had the UMTS 2100 it would not even get the signal at all.
But DL speeds really sucks ass(srry for language) on UMTS2100 it can't go beyond 35KB/s.
If anyone has a good answer is highly appreciated.

Ok well I am considering purchasing a unlocked AT&T Tilt, but I have been reading a bit about the 3G. Currently I am a T-Mobile customer and have read they will be operating on a different band frequency for their 3G. T-Mobile will be using 1700/2100MHZ while AT&T operates on 1900/2100MHZ. Will the 3G on the phone still be compatible?
Please someone clear this up
Appreciate it
Kaiser uses (under the Band options for the phone settings)
GSM (So gprs, edge) 850, 900, 1800, 1900.
UMTS (3G, HSPDA where available) 800, 850, 1900, 2100.
So it would be partially compatible, but only on 1900 cells, not the 1700 ones. These might co-exist like in the UK where some operators use all the frequencies for better bandwidth, or they might not. I'd check with T-Mobile what frequencies are operating in the areas you'll use the phone.
Well I live in the US and they still have not rolled out the 3G network here, they said sometime by summer. So if they use 2100 then the 3G still should be able to work? Since they still will be using the frequency except the 1900.
So good news for all Diamond euro owners in LA (and other places of course)...the tmobile network supports the 2100mhz band for 3G so no need for a US version!!

Sorry if this is old news, but i just realized it =)
this is great if true?
T-Mobile devices use the 1700Mhz/2100Mhz frequency band (for 3G) and I thought Europe 3G devices use 900Mhz/2100Mhz. Could U clarify further...
you said it correct...tmobile does use 1700mhz/2100mhz, and the euro diamond supports 2100mhz which should work since tmobile will be using it...i spoke to a tmobile tier 2 rep, he confirmed it as well...
That can't be right. T-Mobile AWS 3G uses the 1700 MHz band for uplink and 2100 MHz for downlink. I doubt T-Mobile US set up aside any channels in the 2100 MHz band as uplink channels.
It's kind of academic, as I can't get 3G on T-Mobile USA using a Euro Diamond in NYC, where we've had 3G deployed for a few months now. I've never heard of anyone else doing it either. Oddly, there's a "UMTS(1700)" selection in the band settings in the phone control panel, but if I try selecting that, it just jumps back to using T-Mobile's normal PCS band with EDGE for data.
If that tier 2 tech can get you onto AWS 3G with your Diamond, definitely let us all know about it, but don't get your hopes up too high.

AWS?? well the tier 2 tech did say it...i dont know if he was just talking out of his ass or not...but we'll see in the coming weeks...ill try to get tmobile rep on the phone again to ask them how i can get it...or if i can, even though its supported..

As I understand it, if a phone says it supports 2100 it is referring to the UMTS Band 1 used in Europe which is 1920-1980MHz Uplink & 2110-2170Mhz Downlink (see UMTS Frequency Bands - Wikipedia). The 1700AWS Band (UMTS Band 4) uses 1710-1755MHz Uplink and 2110-2155MHz Downlink. So, while they do overlap some they are not identical (A Visual Guide to AWS - PhoneScoop)
So, I don't believe that a phone with 2100 EU support will work with T-Mobile 3G because it doesn't support the 'right' 2100 nor the 1700. Likewise, I don't believe that a phone with 1700 support will work for 2100 EU.
If you want to get technical the "US" Diamond won't work for 3g on T-Mobile either. The 3g band is only for 850/1900. (so i guess we're screwed either way) I'm in Salt Lake City and I don't believe Utah is slated to get 3g until 2009 at this point. I bought the diamond knowing full well that 3g was going to be a slim possibility on this phone. However, a user with a DIAM100 is claming that he's been getting 3g service on T-Mobile in NJ. He said that he'd post screenshots.. I don't know if he's done that or not. I guess all we can do is wait and see.

Do you know who this user is? maybe i can PM him and get some details...i knew i wasn't going to get 3G with the diamond, but after talking to the rep. i kind of want to look into it more since there may be a possibility.

Honestly I'm gonna go ahead and call BS on him for that, I've never heard of anyone getting T-Mobile 3G and I know quite a few people with the Diamond/Raphael on T-Mobile in 3G areas.

I have the USA sold "quad band" euro diamond distributed by htc USA. This is essentially re-flashed euro diamond hardware sold to support american networks, not the 850/1900 newest USA 3G diamond compatable with AT&T. I have looked into this issue and also talked to T-mobile and there seems to be alot of confusion regarding T-mobile's AWS USA 3G network (or maybe they have simply confused me). Here is what I have found out: Assuming they are correct, they are telling me 3G voice for T-mobile usa runs in both the 1700 AND 1900 mhz band, and therefore my euro diamond shoud be supported at 1900mhz for voice 3g support. This 1900mhz is part of the "quad band" voice radio hardware on the euro diamond. Data (AWS 3G for USA) "HSDPA" , which T-mobile has not yet released, runs in the 2100mhz bandwidth, and Data AWS "HSUPA 3g" runs in the 1700mhz bandwidth. Therefore my hardware would not support HSUPA @ 1700mhz, but would support the HSDPA @ 2100mhz. As to the idea that euro bandwidths are different than USA bandwidths, well apparently they are. For example "2100mhz" networks in europe might be actually using 2110mhz-2170mhz, whereas in the USA T-mobile's network may use 2100-2140mhz actual bands. However because these are close and still in the 2100mhz band, there should still be compatability with 2100mhz hardware radios regardless of networks varying the bandwidth slightly.
Of course this may be too optimistic, but it would be very cool if true and I am hoping for the best .

Unfortunately, they've provided you some bad information. Each frequency band/range has a pair of uplink and downlink frequencies - you can't use one without the other - you have to use both. Generally, the uplink and downlink frequencies are relatively close to each other however, the 1700 AWS band has uplink and downlink spread quite a distance apart. Uplink is in the 1700MHz range, downlink is in the 2100MHz range and both have to be used. In the US, 1700 & 2100 is essentially one band.
1900MHz (the PCS band) isn't 3G for T-Mobile (although they technically could put it there at some point.) Right now, 1900MHz for T-Mobile is EDGE voice and data. Most other carriers do have 3G on the 1900MHz band, T-Mobile just doesn't have enough spectrum available in that band.
In short: A phone that supports UMTS 2100 will not work for T-Mobile US 3G. A phone that supports AWS/UMTS 1700 will work for T-Mobile US 3G but not for European 2100 3G. (And 1900MHz PCS will give you traditional EDGE on T-Mobile US.)

You may be out of luck on 3G. To the best of my knowledge, I believe Roger's 3G network runs on the 850 and 1900 MHz bands. However, the G1 runs on T-Mobile's 1700 and 2100 MHz bands. So Edge is the best you'll get (speed-wise).

T-Mobile's rollout of UMTS in the US will focus on the 2100/1700 MHz bands, whereas UMTS coverage in Canada is being provided on the 850 MHz band of the Rogers Wireless network. I think 1900 was added later as well.
My HTC HD is edge (2G only). But I use a lot of WiFi when ever possible.
Should I buy a captivate or a i9000 galaxy s?
It is for the use in the netherlands but I heard the captivate had some more specs..
Thanks in advance!
Galaxy S and captivate are pretty similar.
i9000 has front camera (if you use it), physical back button, better support (more users) and you are more likely to have warranty support in the Netherlands.
i897 IMHO looks better and is heavier (feels more expensive). Also it comes in 16gb (i9000 comes in 8gb/16gb) and has lots of AT&T crapware on it....easy enough to remove...but you have to do it
Take the one you like the looks of better.
I really like the looks of the captivate but I am worried that it's going to have 3g network problems here..
If I would import the phone, would it work perfect with the signal here to?

The issue will be the 900 band will be missing in the Captivate which is where a lot of carriers have 3G in Europe. In the US, it will work fine. i9000x 3G won't work in 850Mhz markets.
Captivate runs on the following data bands:
3G (850/1900/2100 MHz) <-AT&T works fine.
Galaxy i9000x runs on:
2G - GSM 850/900/1800/1900
3G - HSDPA 900/1900/2100 <- Missing 850 for AT&T
Vibrant
3G - HSDPA 1700/2100
If you seriously want a world phone for data, there is only one in the market at the moment that I'm aware of. It's the Sony Xperia X10a. It's a dual mode phone and uses GSM/GPRS/EDGE 850/900/1800/1900 and UMTS/HSPA 800/850/1900/2100.
I'm a complete dummy in this subject so here comes the stupid questions..
What would happen if I tried using it in my country?
I'm using a omnia 2 now with:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
So if I tried using the captivate, would my 3g be gone?
EDIT:
I was looking through the specs at the AT&T site and it said:
GSM/GPRS 850/900/1800/1900 MHz
3G UMTS/HSDPA (850/900/1900/2100 MHz)
So according to these specs it says that it also has a 900mhz frequention.
EDIT2: Vodafone in my area (my carrier) uses 2100 as 3g band and gsm 900/1800.
I foung this info using gsmworld
can someone please explain it to me?
Ik need to choose before friday!
I have been posting in the optimus forum for help. I just noticed last night in a topic yesterday that LG Thrill and LG Optimus 3D are the same, except Thrill is 4G.
My phone is called LG Optimus 3D p925g, it's from rogers and I got it October 2011. It's 4G.
is mine the same as Thrill?
What happens if I use LG Optimus 3D 3G roms on a 4G?
Nothing happens. It's the same.
ok Thrill must be an american brand name or something.
when I flashed cyanogen mod ROM I remember seeing my 4G turn into 3G icon. Does it actually change to 3G or no?
also is this forum more active for help? I wonder why they have 2 forums if 4G/3G is only difference.
It's not even real 4G though. So it's all good.
The other difference is that the basebands are different.
One is international, the other is not.

not real 4G? What are you talking about.
I don't know what basebands are so okay.
Well if it says 4G, you're getting almost the same speed as 4G. There's a detailed explanation somewhere. I gotta find it.
Its 3.5g the way i have it my p925g. Always says 4g i dont know why even if i dont havr 4g speeds
4G implies 4th generation technology and standards. Ignoring the fact our '4G' is actually HSDPA+ (which is pretty much what 3G was supposed to be, but they did the same marketing BS with 3G)... we are nowhere close to the simple basic, no BS 4G standards of 100MBPS+ data speeds, with true multi-tower connections.
As well, all 4G means for most GSM carriers is that the phone has the HSPDA+ protocol enabled, and the towers in that region have the same... which is a simple software upgrade. You could be on a 500Kb connection, but they call it 4G simply because it has HSPDA+ protocol delivering those 2G speeds with a 3G technology.
The closest thing to true 4G on the market is LTE, which is totally new radio technology and tower technology, not simply a software upgrade that increases speedo's top speed from 5Mbps to 45Mbps, even though the motor is still only capable of 2Mbps.
The motor, btw, is the tower backhaul, and that is the real bottleneck in all of this and is what will determine your actual speeds. As it stands, there isn't enough hard line bandwidth out there to give true 4G speeds, and likely will be 5+ years before there is.
By then we will be on "6G" and some will still be running sub 1Mbps connections despite the hype.
ya we got lte phones hear now system isnt even up but rogers is claming its going to be 150mbps downloads
The Only difference
Thrill 4G Networks GSM 850 / 900 / 1800 / 1900
HSDPA 850 / 1900 / 2100
Optimus 3D networks GSM 850 / 900 / 1800 / 1900
HSDPA 900 / 1900 / 2100
HSDPA 850 / 1700 / 2100
maybe it is
HSDPA 900 / 1900 / 2100
OR
HSDPA 850 / 1700 / 2100
because 1700 / 2100 mean AWS and i don't think this phone (p925g) is aws
don't know what to do.
Hi,
someone offer me a Lg p925G from rogers which is unlocked. the problem: I live in france, when I put a french sim in the phone didn't find no network at all even a simple GSM; I tried to register manually to my network (the phone find it) but say that 's impossible to connect it. The phone is under the last V20C rom from rogers.
My question is simple: is that a hardware problem with the frequencies? or just a problem from the rom?
thanks a lot!
