I'm actually a little embarrassed to even have to ask this question, I'm also pretty sure I know the answer but better safe than sorry. Can anyone confirm that the Tmobile version of the TP2 is able to access the ATT 3G network? I'm 99% sure it will but that weird Tmob band makes me nervous, any input would be appreciated.
No, it will not. However the ATT version shouldn't be too far behind the Tmo launch so don't worry too much
no offense but what is the basis for your statement, the Tmob version will have
850/900/1700/1800/1900/2100 bands which are basically the ATT bands plus 1700, why would the Wing II not work on the ATT network?

Please show me where you found this data? Tmobile USA 3g network doesn't use the 1900 band for 3g; they use the 1700 band which is why Tmobile has to have devices specifically made for their network and why the Tmobile USA version won't work on ATT USA.
Again to clarify:
Tmobile USA = 1700/2100 for upload/download for its 3G
ATT = 850/1900 for upload/download for its 3G
Now Tmobile USA does use the 1900mhz frequency but that its GSM frequency it is not related to the 3g frequency. Confusing i know, but you asked.
One of the images advertising it does state all those bands, but does not differentiate which are for gsm and which for 3G (which can be misleading and confusing, ergo the clarification by jim_0068 ^). Though if they share the 2100 I have no idea whether you can get limited functionality or if you HAVE to have both of them. *shrugs*

actually this is not entirely true either,
AT&T is using 850 and 1900 Mhz for their 3G network,
it was revealed recently that they are pushing the 3G network to the higher frequency (850) and plan to have the 3G completely on 850 by 2010.
if AT&T is using 2100, we would've been able to use the european HTC devices which has the 2100 band.

As far as I'm aware:
GSM: 850/900/1800/1900
UMTS:1700/2100
And therein lies the problem... While it supports all the bands that would be required, only a small subset actually apply to a 3G connection/signal...
Minimally, that would be the specs for it to work on T-Mobile, and quad-band GSM is just standard on 99% of phones these days...

You're correct and i edited my post it is 850/1900 for ATT US 3G
I gaurantee you that the T-Mobile Touch Pro2 will not work on ATT's 3G Network At All... the frequencies for ATT will only support the 2G Network and therefore only phone calls and text messaging will work.
let's not go that far, let's not forget gprs (same speed as dial-up) and more importantly EDGE (for some that's more than enough).
when I go into the phone settings -- band I have these options on the Tmobile TP2:
GSM (900+1800)+UMTS(900+2100)
GSM (1900+850)+UMTS(1900+850)
UMTS(2100+800)

hmm, now I think the T-Mobile Touch Pro2 works on ATT's 3G Network.
It should also work worldwide too.
oooh, European bands, "standard" North American bands (they're not really standardized, neither in the US nor Canada and Mexico is barely getting 3G into place), and no idea what the last one is for, sounds like cdma...

I think those numbers are for software only, in fact you probably don't have the hardware to support the frequencies of the wrong carrier.
seems that 800mhz is for Japan
and it doesn't allow for all of the North American bands (it's missing the 1700 one).
Could be just a software thing without hardware support, though that might be a tad odd, any way to check if it is?

My Xperia X1a shows UMTS (900) even when I check the settings... IN FACT only the X1i supports
It's very likely that the numbers you are seeing are actually all of the frequencies that are "summed up" and therefore the TP2 for T-mobile does not have the actual hardware.

Those options have been around with the custom ROMs, I have that too on my Fuze, if your hardware doesn't support it then it'll just be an eye candy.
Bottom line is this, if you want to utilize AT&T's 3G, then you'll need to wait for AT&T's Fortress because you need the 850 and 1900 band (UMTS band II). If you want to use T-mobile's 3G you still need a TP2 that has the 1700 and 2100 band (UMTS band IV), and no you cannot use european TP2 to access US T-mobile's 3G band because european's (and asia's) 3G utilizes UMTS band I, they are on a slightly different frequencies even though they are categorized both on 2100Mhz.

Finally decided to get a T-Mobile US TP2
Q0. Other than the looks, what else is different between the International Unbranded HTC TP2 and the US T-Mobile TP2
Q1. I've been told the US 3G bands are different from the Asian / UK 3G bands. The Asian bands if I'm not mistaken are "HSDPA 900 / 2100". Can anybody cite the US bands? Also I know that 2100 is common for both US and UK... will that be enough to use 3G in Asia?
Q2. Obviously I would need to get the phone SIM unlocked. For once I couldn't find anthing on XDA to unlock the TP2. Any light on that would be great
Q3. I noticed that Hard-SPL is now available for TP2. I'm assuming that means I can flash it with any ROM. Would doing that automatically unlock the phone to be used with any SIM?
Need answers to these real fast guys... got a good deal on eBay.
0. mostly looks and 3g bands
1. tmobile 3g is strictly for tmobile 3g. anywhere else and its edge for you
2. no free sim-unlocker yet
3. Hardspl is for flashing roms...completely separate from sim cards
Oh man... that sux. I was really hoping that atleast one of the T-mobile bands would be compatible with the Asian 3G bands. Do you have any idea what bands T-Mobile operates on?
HSPA/WCDMA
1700/2100 MHz
Note the 2100 band is part of AWS which means it's not compatible with Asia 2100. T-Mobile 3G requires both 1700 and 2100 to operate. One band is upload and one is download.
Quad-band GSM/GPRS/EDGE
Quad-band 850/900/1800/1900 MHz
What exactly is the AWS?

the t-mobile rhodium supports UMTS 1700 and UMTS 2100 so if canada and/europe use those bands for UMTS (3G) then yes it will work. If not, the device is quad band GSM so no problem using voice and EDGE for data.
Also make sure the device is unlocked if you plan to put another carrier's SIMcard in the device.

Not sure about Canada...but TmoUSA 3G bands are different than Euro-3G.
Unrelated, but worth mentioning: the T-Mobile USA international roaming charge for data is steep -- $15/megabyte.
If you got a Euro sim card that would fix the $, but not the radio (for 3G).
The T-Mobile version supports AWS and 2100 3G so works fine in Europe and most other locations. Had 3G T-Mobile and 3G Orange in the UK, but I would suggest a local SIM too. For the UK, both T-Mobile UK prepaid and Virgin UK prepaid work in a locked T-Mobile TP2 or get it unlocked for more choices.

You used a T-Mobile USA version of the TP2 in Europe and had a usable 3G data connection?? Hmmm...that's the first I've read of this.
If this is well-known (and if so, maybe I'm just clueless ) can you provide a link to more discussion, that is...uhh...evidence...of it? Not about what bands the USA version supports -- I know that part -- but other reports/disucssion of it actually working.
On the other hand, are there any reports of a Euro-TP2 that can work on 3G bands in the USA?
USA TMO TP2 will work on TMO 3G in USA. It may also work on WIND Mobile for 3G data here in Canada, not sure about voice as they are using some strange network setup.
As the phone is UMTS 2100 capable, it will get 3G data and voice in most places in Europe and Asia.

Have you tried a TmoUSA TP2 in Europe or Asia -- yourself -- and accessed 3G data?
I'm still doubtful, but I actually hope I'm wrong 'cause I'd love to be able to get 3G data on my TmoUSA TP2 while traveling in Europe...as long as I get a Euro sim card. Otherwise, faster data just means more roaming-$$.

Check the specifications. It supports both 1700 and 2100 UMTS. That means it will work in Europe. ALL Touch Pro 2's have 2100MHz UMTS and quadband GSM, every single one of them, including the CDMA ones. The carrier specific ones add certain bands.
European Touch Pro 2s have UMTS 900
CDMA Touch Pro 2s have CDMA bands
T-Mobile USA has 1700MHz AWS band
AT&T has 850/1900MHz UMTS
TP2 overseas vs versions
I believe, as I've use phones often in the US and overseas, that T-mobile uses 1700 UMTS in the US, but that their TP2 is also 2100 UMTS. Just as At&t Tilt uses 850 & 1900 UMTS (At&t requires both frequencies), but also has 2100 UMTS. As such, both should work in most European, African and Asian countries (verizon and sprint you,re mostly screwed).
I believe the older Tytn II (tilt) was sold world wide as a 850/1900/2100 phone, so you could basically buy it anywhere and use it here on At&t only for 3g or T-mobile Edge only. Unfortunately, the TP2 is sold mostly as a 900/2100 UMTS worldwide outside the US, so you are stuck buying the US versions that correspond to the US networks. The bonus of the At&t tilit 2 version is that it is 850/1900/2100, so it will work almost anywhere. The drawback of the T-mobile TP2 is that 1700 is used by almost no one and while you can use it in most of the aforementioned places, you can't use it in the Americas outside the US & Canada.
Check out this handy wiki UMTS page: en.wikipedia.org/wiki/List_of_Deployed_UMTS_networks
Just a note, I almost always pick up a pay as you go sim in other countries- much cheaper and very little hassle. Worth it for anything over a week stay. Maybe not as much so in some of Western Europe.

That is correct. Apparently they are only able to have 3 3G frequencies (though NTT DoCoMo is currently working on a chip that can handle 8 frequencies!)
At first Europe only used 2100MHz 3G and AT&T had set up on 850MHz/1900MHz. Since those were the only 3 bands, HTC would put all three of those bands in its phones up to the Tilt (Kaiser). Once they made the Raphael though, there was 900MHz 3G in Europe and T-Mobile had chosen the AWS band.
Since they can apparently only put 3 bands in, and Europe now needed two for 900MHz/2100MHz, they could no longer put but of AT&T's frequencies in. So they must have just dropped them.
The AT&T version (FUZE) has 850MHz/1900MHz and also has 2100MHz, which is the dominant band for 3G in Europe. I am not sure if they are using 900MHz there yet, but they decided that was more important to put in the European ones than AT&T's bands.
T-Mobile's 3G phones get AWS and 2100MHz. I think AWS might use 2 of the bands because it is split on 1700MHz and 2100MHz (but a different 2100MHz apparently, maybe low 2100MHz vs high, I'm not sure)

It doesn't just support 1700 and 2100, it uses both to work: 1700 for up/send and 2100 for down/receive. So, how does the Tmo USA radio cope without 1700 band for up/send when it's expecting it?

So, the full story (?) is that T-Mobile uses 1700+2100 (up/down) in the USA (which is what I already understood/knew) and in addition to that pair there's a separate slightly-different 2100 band that's used outside the USA? -- That, I didn't know.
If that's the explanation, that makes sense. But confusing that there's 2 different 2100 bands...
I may have to use some frequent-flyer miles and go check it out...

According to Wikipedia, UMTS Band I (commonly known as 2100MHz) uses 1920 - 1980 for uplink and 2110 - 2170 for downlink while UMTS Band IV (AWS, 1700MHz) uses 1710 - 1755 for uplink and 2110 - 2155 for downlink.
Band II (1900MHz) uses 1850 - 1910 for uplink and 1930 - 1990 for downlink and band V (850MHz) uses 824 - 849 for uplink and 869 - 894 for downlink. The uplink and download for these are close, unlike bands I and IV.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
I just assume they are only able to have 3 different frequencies since I have yet to see a UMTS phone with 4 frequencies. But as I wrote this, I'm not too sure because there were phones with Band I, Band II, and Band IV which would mean that there are chips capable for 4 different frequencies? Who knows, maybe someone with actual technical knowledge about this can say.
Also according to that page, there are five different UMTS bands deployed across the world. A bit of a pain. That is more then GSM ever had and who knows if it will grow to even more. LTE also will be coming in before GSM is phased out, so we are going to have to have phones that have GSM, UMTS, AND LTE. GSM will be no problem, quadband has been standard for a while, but having a phone that has both your carriers UMTS and LTE frequencies is going to be tough unless you buy it from your carrier.
What they should have done is just used the band names, and not their frequencies. It would be much easier to know that Europe runs on band I and T-Mobile USA runs on band IV and the T-Mobile Rhodium supports both Band I and Band IV.
Right now "officially" there are only the HTC HD7 and Dell Venue Pro available on TMobile USA.
Does anyone know which other phones would work (after unlocking) with 3G on TMO US?
er...none?
I think so far only these two WP7 devices supports AWS bands.
On other platforms is different, as in the case of latest High-End Nokia devices (but Symbian OS):

However it is a fact that the multi-band support, increases the cost. Is better to invest in features that do will be use
Best regards
Many WCDMA devices support the 1900 band, if you don't care the 1700 band.
but he asked about 3g...the phones don't offer 3g. Sure 2g works
3g nope
And consider 1700 AWS band with no longer be T-mo 3G after merger (AT&T needs the AWS band for LTE), you will be insane to spend $$$ on your own handset.
Even on AT&T side, there have been a lot of markets switched over to 850 band for 3G. So, even with a phone that support 1900 band 3G is no longer safe even on AT&T.

In my area, all 3G towers were 1900. Then AT&T switched all of them to 850 last year. This year, they switched back to 1900 again. AT&T has indicated in the past that it intends to deploy more 850 band 3G to improve coverage.
I thought the 1900 towers would stay 1900, and new ones would be 850
Virtually all 3G-850 american handsets, also have 3G-1900 band. In other hand, the carriers such as Telstra (Australia) and Telcom New Zealand have also 3G-850, with 3G-2100 band (not 1900); but these last are a minority.
The AWS bands with WCDMA technology (3G), are only used by TMoUS (as we all know); and fatally these bands will be used by "new" Latin American carriers like Nextel Mexico and others like VTR and Nextel Chile.
No larger carrier exists than TMoUS, that use AWS bands, so that all developments in AWS bands, should be first implemented in TMoUS ...until now

That's true but most ppl who buy unlocked/unbranded handsets buy the European models which typically only come with 1900Mhz band 3G for NA. Those handsets rarely ever supports 850Mhz.

It's not the ROM but the actual hardware that has the limitation although sometimes ROMs can have band limits as well.

On both my HD2 and HD7 I will get an "H" signal. I was talking to T-Mobile support and they told me that was 4G and I was getting it because of the ROM. I asked why they would restrict the 4G if the hardware would do it and they said it was to control the number of devices on each network. I can only get it with an unbranded ROM. I'm not arguing, just telling you what they said. HD7 according to T-Mobile is NOT a 4G capable phone but mine gets an "H" signal all the time.

HSPA --> 'H' indicator on your handset (with custom ROM)
HSPA+ --> what T-Mobile advertises as "4G"
The H does not mean 4G. It means you have HSPA. In the carrier-specific ROMs they overwrite the H bitmap with one that shows 3G instead, to "help" their customers and avoid confusing them.

Will I lose any lte band support if I convert to tmobile?
Yes, flashing T-Mob US (I assume you mean US, since you are talking AT&T) firmware or RUU will change band support, and you will lose some LTE bands.
According to the specs on GSMarena, with the T-Mob firmware, you will have support for LTE bands 4 and 17; and will lose support for 2, 5, and 7.
What bands do you need, and what carrier are you using?

What if I merely flash a tmobile based rom

Just flashing the ROM, you won't change the band support.
But again, I'm curious what carrier you are actually using the phone on?

Should work fine.
Being on T-Mob US, and using AT&T radio baseband (part of the firmware that determines band support) should be fine for the most part. Reason I say this is:
1) ATT radio supports the same LTE bands as the T-Mob radio (4 and 17), and then some.
2) ATT radio is missing HSPA (3G) Band 4 (AWS). This used to be the band most widely used by T-Mob for 3G. But my understanding, is that they are well underway in migrating 3G service to 1900 MHz (Band 2) which is supported by the ATT radio.
3) The only "negative" to staying on the ATT radio, that I can see, is that if you happen to be in area where T-Mob is still using AWS for 3G , and you don't have LTE service in that area, either. In that instance, your data will drop down to EDGE (2G). I don't really have an idea of how widespread this situation may be; but I have a feeling its relatively small.

Yea thats why I got an unlocked ATT m8 instead of a tmobile one for the extra lte bands. I have yet to run into band 2 lte and all the aws hspa has been reused for lte. Luckily.
