Saw this news story, does anyone know if it is credible? The NextG Service is on the 850MHz band which is the same as Rogers/Fido in Canada and Cingular in the US...if all this is true then one of these unlocked would be 3G Compatible in North America...Thoughts?

Well that would suck for me because about 3 hours ago I got an iPhone because I really needed 3g already I do ally of browsing and videos but I like the touch he better....
What is the exact issue with North America and the Touch HD? I thought HSDPA was fully supported in our continent under most major providers. Just curious as I'm looking at purchasing one in the future.

The Touch HD that is out now operates on UMTS 900/2100. Telstra in Australia and the North American providers (except T-Mobile) use UMTS 850.
hopefully it is just some software that HTC did. cuz we do have that option to change it to 850MHz 3G in the phone but just nothing happens to it. If a flash can fix it then it should be ok. EDGE for me is pretty fast anyways in Toronto most of the time.

850 mHz is just one of the 2 bands needed to work on US 3G. you also need 1900 . my understanding is one band is for upload the other for download. don't get me wrong, it would be fantastic if the Aussie version was fully capable on US networks. i'll believe it when i see it. heck, expansys even has a note saying they have to confirm the 850mHz 3G band.
850/1900Mhz....
could someone please explain the upload/download at different frequencies paradigm to me?

This is incorrect. With at&t you do not need both. With just 850mHz you will be more than fine.
Now with T-Mobile you would need both 1700 and 2100 not just 2100 or just 1700 both. Just more reason to hate T-Mobile.
I am ready to take the plunge and drop the $ for an HD. I also will switch my number back to at&t from verizon. I guessi cna say almost ready. I really dont want to spend $800 for no 3G
Does anyone know how hspa in Canada with Rogers/Fido works? i.e. are dual frequencies required or is 850MHz enough to get top speeds? Thanks...
Has anyone brought one into the US and had any success getting a 3G signal ?
Some carriers in the US and Canada use 850mhz such as AT&T and Rogers but they also use 1900mhz. It really depends where you live... Whiich city, state etc
1900mhz is growing in popularity in the states.

You are exactly right. YOu need both 1900 and 850mhz

Sadly, no 3G for me.
You do not need both 1900 and 850. Its only tmobile that u need both frequenes but they use 1700 and 2100. As long as u have ether 850 or 1900 (depending on what freuency ur area uses) u will have 3g with at&t.

No, the *network* you use may be present on more than one frequency, but its not 850 being uplink and 1700 being the downlink.
When we talk about UMTS the downlink is around 850/1700/2100 but the uplink is always a few MHz below that. (to be pedantic, the UMTS specification specifies the exact downlink/uplink separation)
I can't imagine HTC producing a UMTS 850 phone that won't work on ATT/Rogers and Telstra . Telstra only needs the 850 band so HTC can add in whatever extra the US providers use. It will probably be the same bands supported by the HTC Hermes and other phones common to these providers.
for AT&T, you do NOT need both frequencies (850 and 1900) for 3G. They don't HAVE both frequencies in most areas. It's one or the other.
And yes, T-Mobile US sucks ass...

Well I stand corrected then. This is good news then. Just need somebody in the US to buy a Telstra HD and see if it works. I guess it will be dependent on the area though. If you don't have 850mhz.
Lol i guess it took a senor member to say it for anyone to believe it. I only said it in the first page lol. Lets see what happens when the aus model comes out.
So it is decided then IF the Blackstone is introduced by Telstra and working on their 850MHz 3.5G Network THEN it has the opportunity to work in both the US on Att and Canada's Rogers/Fido...I will wait for this device, purchase it and let the board know if someone else doesn't beat me to it!
P.S. does someone think that this release may be with the Android OS for Telstra? It was the Telstra reps that were commenting at CES 2009 regarding Palm Pre and how the next Android phone that they were testing kicks it...who knows probably coincidence...
not quite sure how to search this so i guess ill ask (or reask) the question.
1. am i able to reflash my Leo to work with USA ATT 3g bands if a rom ever comes out in the future?
2. can someone confirm to me if step #49 of this tips and tricks thread (http://forum.xda-developers.com/showthread.php?t=583638) and that piece of 3G activation software works and can allow my Leo to work with ATT 3g? (i dont think it does)
thanks!
1. Nope. It's all hardware.
2. See above. Nope.
It's all edge, my friend!

The HTC HD2 will not use 3g in the US. But since the phone is so fast, browsing the internet using edge is faster then with 3G on a sony X1a (my last phone).
do you already have an HD2? Regardless of anything you've read thus far, 3G is hardware dependent. No USA 3G internal radio? No USA 3G.
If you don't already have one, just wait until next month because the HD2 is supposedly coming to Telstra (who operates on 850mhz 3G, just like AT&T). HTC have said that the HD2 is coming in Q1 2010 but it's more than likely going toward T-Mo (based on leaked pics) or other carriers other than AT&T.
ah well i was under the impression that the hardware was both same for euro and us releases and just the software controlling it was different...(and how come they didnt name it the T8582 vs the T8585 as with the HD1 standard for the 2 different radios?....how they gonna distinguish the different hardware HD2s?)
come next year i may just sell mine for the new one (testra one you said). i dont suppose that tmo one will work with att 3g as its on a worldwide 3g band huh.
truly is a nice phone no doubt still
T-Mo US operates on 1700mhz AND 2100mhz for 3G (someone correct me if im wrong...one for uplink and the other for downlink). ATT can operate on 850mhz OR 1900mhz. The European version only has 900mhz and 2100mhz. As you can see, if you use the HD2 in the US (t-mo or ATT) right now, you're restricted to only EDGE unless they both possess their respective 3G bands.
this is what someone on htcforums.com said to me...confirm? deny? reject? love? i guess im just receiving conflicting info as to why this guy would believe this then?
"What you are asking about is a software differentiation. According to PDADB.net, the HD2 US version is scheduled for March 2010. http://pdadb.net/index.php?m=specs&id=2 ... us_htc_leo
The GSM version currently available is capable of T-Mobile US 3G frequencies; as T-Mo is the only US company to use WorldWide frequencies {2100MHz}. The version that is scheduled for March will be for AT&T frequencies. Since the hardware on these two versions are identical, you could flash a WorldWide version with a US version radio, & use a WW version with AT&T."
Your link doesnt work. I don't want to beat on a dead horse, but countless of T-Mo USA users have the HD2 and they could only have access to EDGE. Like I said, for T-Mo USA, their 3G has a split frequency (one for upload the other for download) that's why you need both 1700mhz and 2100mhz.
thats the link

http://pdadb.net/index.php?m=specs&id=1783&view=1&c=htc_hd2_t8585_htc_leo_100
this on HTC's site
Europe: Network Bands
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
Asia Pacific:
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
which means it can work here no? since USA att 3G is 850 or 1900?
* HSPA/WCDMA: 900/2100 MHz <--3G
* GSM: 850/900/1800/1900 MHz <-- EDGE
Your problem is that you're looking at the voice/2G/EDGE bands. The HD2 is a quadband phone, so you can pretty much use it anywhere in the world. Your original question was regarding 3G, which the HD2 does not support here in the USA (yet).
3G would be this line HSPA/WCDMA. See how it's only support 900/2100mhz?
GSM is only voice correct? .... getting my voice/data abbreviations all mixed up...

GSM is voice and EDGE (data)
For ATT the key is 850mhz 3G as that what ATT has been adding, I don't believe they are doing any new 1900 towers. You can bing it there are lot's of articles about the iPhone congestion and changing/adding 850 towers. If we are lucky Telstra an, Australian carrier, will pick up the phone soon because they use the same 850 just like ATT. This is how people got the 3G on the HD(1) to work on ATT in the united states. HTCPedia posted a Telstra HD2 rom on Dec 9th, so hopefully they are close to releasing.
Simple question, but hard to answer: will this US phone work in Asia with UTMS 2100, at 3G (HSPDA) speed?
I know an International HD2 going over on TMobile or AT&T roaming will only get EDGE.
I want to know a similar thing: Will the T-Mobile US HD2 work on Western European 2100MHz 3G band?
(I won't be using it in the US, so the fact that the international version doesn't work on US 3G is of no interest to me.)
A simple answer: it will because it supports band 1 and 4 3G.
Simple Answer: Yes
Thanks everyone who replied. I'm making a trip to LA in about 3 weeks time to grab one at a T-Mob shop. Hopefully the stocks will not be an issue by then...
I'll be moving back stateside this August and I'd love to use my sim free Legend on a gsm provider back home.
T-mobile US 3G bands are (900/AWS/2100 MHz)
The Legend is specified for use at: HSPA/WCDMA: 900/2100 MHz
Can anyone clarify if I'll be able to get 3G on a T-mobile US sim?
Or even knowing the bands are similar does the fact that T-mobile uses AWS and not HSPA/WCDMA mean I wont get 3g?
Any type of clarification would be helpful

Hey man, you might have figured this out already but, as far as I can tell, you can't use the T-mobile US 3G bands on the legend. I got my legend over the interwebs and put my t-mobile SIM in there, and although there's 2g data, no 3G. I don't really mind though, it's an awesome phone and it gets plenty of second glances since there's nothing like it here in the states. I'm also around wi-fi most of the time i need it, but it would be awesome to get that 3G working.
I've looked around a little but can't find anything. Does anyone know if this is even physically possible? And if so, how? Thanks.
I have searched many place and I am getting conflicting info.
I am going to Taiwan in couple days and would like to know if my US TMo HD2 would work with 3G network over there.
Through my research, I believed that most carrier in Taiwan uses UMTS Band I (UMTS2100) for their 3G network.
I know T-Mobile uses UMTS Bnad IV (UMTS1700), but what I am not sure is does the US TMo HD2 has both Band I and Band IV or just Band IV?
In the WinMo setup, there is an option to change Band Frequency and it has both UMTS(1700) and UMTS(2100) as choices. Does that mean it has both Band I and IV?
Also, am I correct that if the frequency is available in WinMo, it would be available in SD loaded Android? I couldn't find when in Android to see available band frequencies
Thanks for any help.

It should work fine. The t-mobile hd2 has both 2100mhz and aws (aka 1700/2100 together. for tmo 3g) for 3g and more for 2g.
Thanks guys.
Neither HTC or T-Mobile display the band frequency using the standard format so it's kind of confusing.
Thanks for clearing it up for me
Happy Holidays

To provide some evidence, I just got back from Taiwan and it works fine on FarEastTone and Chunghwa.
3G works well here in Taiwan.
I am sending it from Vibo network.
Just a note, only Vibo network have pre pay data sim.
