I read that the official release of the S730 for the US will be 3G quad band.
I have a S730 thats is only for 2100. Will be the implementation of the other frequencies be software or hardware based ?
If it's SW would it be possible for my phone to work in quad band ?
Any ideas ?
If they included the radio for the other frequencies than a software flash should make it work, but I doubt they put the radios in for our frequencies here. I would be interested in knowing as well, but we shall see as the time gets closer
This was linked in another post. So their choices are clear, hopefully they chose to use the chip that supports all the freqs; but I doubt it, since the model IDs are different: WING220 (the EU version we all have) and the WING200 (the North American model).
Now let's see someone get the TV out working.
Seriously, we will see if writing NV item 0148 can also fix this issue.
I couldn't help myself. This phone seems perfect so i ordered a diamond that will arrive tommorow. Now my question is if anyone thinks the bands for US are present and need to be unlocked or if this will end up on ebay . Thanks!
There's several topics about it there.
You won't get any 3G in the US with it, and you'll only be able to use the 1900 band for voice/GPRS/EDGE.
Actually you are incorrect. 1900 Mhz is supported w/3G w/AT&T in certain areas. Unfortunately my Diamond is not even getting an EDGE connection. From what I am hearing the Diamond is only supporting 2100Mhz frequency w/3G according to HTC. Which to me makes no sense.. I am blogging my experience with it as it is the first production unit in the USA.
You just said i was incorrect and correct in the same paragraph lol
This is where all the confusion starts.. For GSM/GPRS/EDGE it does 900/1800/1900 MHz - only 1900 would work in the US. For UMTS (3G) it only does 900/2100 - neither of these frequencies are used in the US.
The protocols and modulation used are completly different for GSM/GPRS/EDGE vs UMTS. The dispersal of uplink and downlink frequencies is completly different. Just because it can do 1900 for GSM doesnt mean it should do 1900 UMTS.

So why wouldnt I get Edge? I have had triband phones before i.e HTC 8525 that worked ?

You should get edge. Edge is an extention of GPRS but requires a different BTS (radio tower) setup. Its possible you don't have a strong enough signal, but it sounds like your confident you should have edge in that area.
The only thing i can suggest it to try in a different area - like the centre of town. Also, confirm your APN is setup corectly, the [G] may just be telling you GPRS is available, but not that you can attach.
I know with my elfin it takes a little stronger signal to initiate the Edge icon the first time (ie. after a hard reset). I can't get an edge signal inside my office but once I walk outside for a minute or two, bam I have it. Then when I go inside I still have it.

Diamond had UMTS(2100)+GSM(900+1800),UMTS(850+1900)+GSM(850+1900),UMTS(800+2100),UMTS(850+2100)+GSM(900+1800),UMTS(850)+GSM(900+1800) and UMTS(1700) depend what rom you had in your Diamond and where you bought your Diamond , At&T should be show 3G in US and T-mobile used 3G (1700 Mhz) in New York area
The platform in the phone can support all those bands, so you might be able to see them (like in the test rom) but the antennas are not there. So you won't actually be able to pick up a signal.

I guess all of us US early adopters must hope the hardware is there and can be enabled with a future flash.
T-mobile in the US uses 1900mhz for GSM/Edge and only has 3g in NYC, so I'm figuring that it's a cool stop-gap device until something is available for T-mobile 3G.
so anyone have the rom that had thoose bands....
confused
so im a little confused.... If I buy a diamond on ebay, it wont work in the US? or 3g just wont work? does the diamond accept a sim card?
On AT&T it will give you only GPRS! On Tmobile (NEW) it shows EDGE!! I dont understand this at all!

Voice and EDGE will work just fine as long as you are in a major area that uses 1900 band. You might have weak or no signal when you are in smaller rural areas since those usually extend into the 850 band.
You will not be able to use 3G since the Diamond only supports 900/2100, neither of which are used by AT&T
It looks like if you have ATT you are hosed for both voice and data, as most of ATT voice and data (Edge) is 850mhz. Most if not all of T-mobile voice-data-Edge is 1900mhz so you will have at least Edge. If you're looking for 3g data you're SOL until the US version of the diamond is released.
this fn blows htc has really screwed us here in usa...i was willing to spend 800 for this device and htc doesnt even see this? by the time it comes out here in quadband ...the x1 will be out and not mention the 3g iphone...oh well

We will get the diamond, have to wait for the US version that does the different bands.... wich leads me to my next question. What carrier do you think will get the diamond??? AT&T seems to get all the cool stuff.

I don't think HTC cares about America too much any more because it's iPhone territory. As they haven't used their own branding until recently, I think HTC are looking to gain market control and loyalty, and that's easiest where the iPhone hasn't been a huge success.

Again, HTC seem to like doing exactly what Apple are not doing, so they may go for multiple carriers. As far as I'm aware the Touch Diamond, and its branded versions, are launching on every network in the UK. That's the complete opposite of Apple's 'one network per country' policy, and they consequently seem to have dropped it (for example, in Italy).
AGREED 100%!! I have been saying this on my podcast for quite a while.. It is a huge mistake. I am now saying since I just received my Diamond that I took one for the team.. I will post my review as the days go by...
SIGHHHH

As many of you may have already noticed, many of the Diamond's spec sheets say that the device's radio is capable of operating in all bands. Official word is that the device is tri-band (America or Europe). Is this limitation based on the settings for the rom or radio.
In other words, is it try or quad physicaly? And if it is, is somebody going to release a cab to enable it?
Regards,
OB
The chipset is capable of using other bands, but there is no antenna for these other bands. I am about 80% sure that in that case calibration data for the other bands will be missing in the Radio, and those bands will therefore be disabled.
I've Googled around for the better part of the morning and not found an answer.... forgive the noob question. I'm a programmer, but I don't know much about mobile tech/programming.
I have an unlocked Treo 750 I use on T-Mobile. Software Treo750-2.25-ATT Firmware 1.54.27.00. I'd like to know if it's possible to use the T-Mobile US 3G network. I was told it wasn't possible due to T-Mo using 1700/2100 band, which the Treo can't access.
Would upgrading the radio version allow me to do this? If so, is that the only piece that would need to be updated? Which radio version? From what I've read, it and the ROM talk to one another but radio capabilities aren't determined/defined by the ROM. Is that correct?
Many thanks in advance,
Richard
Not sure but I think it will
Radios do not work like that. The antennas in the phone are calibrated to work on certain frequency ranges. It's the same reason that a normal FM car antenna would work poorly for shortwave or CB.
The radios in the phone are approved (at least for the US) to work on preset frequencies by the FCC as well, so they will not even have the capability to work on any other bands because if they were broad-spectrum radios, the phone would fall into another category of device as mandated by the FCC.
Thus, any phone will only work on the bands that it is designed to.
Hi,
I have a spare sgs i9000 (bell vibrant) fully functional. My friend would like to use it, however his carrier is Videotron who uses the 1700/2100 frequencies.
My questions is the following: is it physically possible to put the t-mobile vibrant's antenna (which is also 1700/2100) into the i9000?
If i manage to put the t-mobile antenna into my bell phone (I assume I also need to swap the antena module??) will it work with videotron?
I hope someone can help!
Thanks in advance
i was asking the same question before
it is technically possible
***bump***
It is not possible. Each frequency being used requires its own chip (power amplifier). If the phone does not have the hardware (chips) to support a particular frequency, there is no possible way it can support said frequency.
Its a hardware limitation which requires more than simply swapping an antenna.
Mind you, newer chips will probably come out in the future that will support multiple bands in one package. The next Gen qualcomm dual core snapdragon supposedly supports both CDMA and GSM 3G bands for example.
