Hi, can I change touch dual the GSM from Tri-band to Quad-band,
for the better reception in USA.
I know the touch can do that, Thank
Now that its going to be available in the US with quad band, does it mean tri band niki can be changed to quad band?

I would like to know this too
It could be possible, but the RF chipset could be totally different on the two models.
There wouldn't be much of a reason for HTC to restrict the current tri band duals with the way the various operators have deals with other overseas operators.

You would think they would have designed, developed the radio chip long ago, and the new edition would only contain software changes to the OS, and Hardware soft updates
--bump--
I too would like to know if this is possible. The best buy website has a touch dual listed with 850. I called their customer support and they couldn't give me any information on release date or even a model number. Will the US version of the dual have 850? I want to know if I can get this $500 phone to work here (area code 318 with ATT) on just the 1900 band or do I need the 850 band for better reception. Any advice would be helpful. Thanks in advance.
b
Any luck? I would like to upgrade to the quad band
theres only one version of the dual that is quad band and that is the US version being sold by BEST BUY.
Thanks for the reply I figured I was out of luck, so I ordered the us version yesterday.
Bought the triband Dual but, soon figured out that it doesnt work well in the states.
I thought I would give it a go.
Thanks
Was working on 850MHZ than....
My HTC touch was working on 850 MHZ than I had a tech at my provider's, setting up my internet.
Since that moment it does not work anymore:
Getting the signal but not able to make calls or receive calls.
The guy tried to fix it. It worked for a couple of calls and than stopped working.
Back to the tech, he told me it s because of the 850mhz on which they operate.
He said that even if it was working fine, it wasn't meant for their network (850 MHZ).
Should I believe him?
(the phone works fine with 1900MHZ band from another company)
How can I fix this?
wish there was a radio upgrade like the latest for the diamond that enabled the 850 band
I was lamenting on my lack of foresight, getting a HD2 without researching the different bands that AT&T and T-Mobile use for 3G coverage, when just the other day...
NOTE: This was on a call to AT&T Support and the tech tells me:
a) Once unlocked from TMOUS, I should do a search on "AT&T APN's" and that if I search diligently, I will find APNs on AT&T's network that support HD2 3G Bands
b) AT&T techs, right in his data center have this working.
So I research a bit, and, apart form everyone and his brother professing to be 3G Band experts, and saying all I will see is Edge if I put the HD2 on AT&T. (Which is troublesome, since Wikipedia claims Edge is being dropped to facilitate more 3G bandwidth, so potentially I would lose even THAT).
Here is what official information I could find on the two:
The U.S. T-Mobile network predominately uses the GSM/GPRS/EDGE 1900 MHz frequency-band. T-Mobile's UMTS (3G) service is now active in over 30 major US cities
Further all official documentation states that AT&T uses:
* 850 MHz UMTS/HSPA/HSPA+ 3G
* 1900 MHz UMTS/HSPA/HSPA+ 3G
Finally look at my screenshot, taken from the GSM 3G toggle on the "Settings Tab" of Manila. I am running a NRG ROM (see signature) and I KNOW this is wishful thinking. This screen in particular is no doubt a function of the many devices NRG cooks for, but really, can anyone explain to me why this technically would NOT WORK (other than "just because", LOL)?
AT&T's CEO recently gave an interview and stated that the company's 3G service is being migrated to the 850MHz band with a target date of 2010:
http://www.intomobile.com/2009/02/24/att-3g-network-going-850mhz-nationwide-by-2010.html
For what it's worth, I think the Australian version of the HD2 might have a band that overlaps with US AT&T bands.
Whos gonna buy me one?

Yes, I have been hearing the same. Problem is, I am not likely to fork out $$ for ANOTHER HD2. I just wanted to get the most out of the one I have. Thx!
if something like this WAS possible, it would have to be through something like a rogue apn setup on non-standard frequencies on ATT's network...but good luck finding anything like that, it wouldn't be able to remain a secret if it existed. also, if the hd2 had the ability to use those native frequencies, it would have had to have been certified as such by the FCC (which of course it wasn't).
To summarize, the only way to make it happen is if ATT did indeed somehow sneak in alternative-frequency apn's across it's entire network. Let us know how the search for those turns out

Sorry.
http://en.wikipedia.org/wiki/T-Mobile_USA
3G (UMTS/HSPA/HSPA+) service by T-Mobile exclusively uses the AWS 1700/2100 MHz frequency-band, making it incompatible with other existing 3G UMTS/HSPA networks already established in the United States.

Its not physically possible. The hardware would have to be changed. They don't make radio chips with all the bands in it. I see this all the time, some random csr from whatever company says it can be done, but its just not true. Cell phones are designed and made for a specific company. They don't make universal radios and just turn off some bands. They don't exist, though I did read a few months back that Motorala was working on making one.
Although I understand the reason for your wishful thinking (and you did do some research which is always great), unfortunately it is just that and I'll gladly (though not happily) tell you why.
As you stated "U.S. T-Mobile network predominately uses the GSM/GPRS/EDGE 1900 MHz frequency-band" which is correct (and it also uses the 850 band for edge as well....though this is usually more 'roaming' aka you're using another companies cell tower because tmobile made a contract with them to allow you). You were also correct in stating that "Further all official documentation states that AT&T uses:
* 850 MHz UMTS/HSPA/HSPA+ 3G
* 1900 MHz UMTS/HSPA/HSPA+ 3G"
Also, ironcroth was also correct in quoting that "3G (UMTS/HSPA/HSPA+) service by T-Mobile exclusively uses the AWS 1700/2100 MHz frequency-band" which alone might not answer your question.
So where is the problem if both use 1900 and 850 bands? Well, the problem is that in the hardware, there is a difference between GSM/GPRS/EDGE and 3G/UMTS/HSPA/HSPA+. In other words, you can't use 1900 and 850 Edge frequency of the HD2's radio chip to get 3G (UMTS/HSPA/HSPA+); they are incompatible. This is why phone spects always list both seperatly and not just all the frequencies that it supports.
The above reason alone will make the TmoUSA HD2 incompatible with AT&T's 3G, but there's even more. When Tmobile says that it uses the (for example) 1900 frequency band for Edge, it doesn't actually mean that it uses 1900-1999 frequencies; instead it only uses a part of that spectrum (buying the full 100 frequency range would be expensive so they only buy what they need). Instead they only use maybe something like 1943-1978. And this range will likely not overlap with the frequncies that AT&T uses for their 3G (you can look up the exact values on the internet if you'd like). This second reason is why a european phone which supports 2100 band for 3g will not work on Tmobile's 3G 2100 frequncy (because they don't actually overlap).
Lastly (and I almost forgot to mention this), the screen shot you posted from your ROM can indeed be changed by a cook to whatever they want (though it won't actually make any difference since it all depends on the hardware). However, in this case, it's likely because htc actually made the error and never updated that screen and just used it from their previous builds from previous phones (this was stated on the forums before and I'm sure you'd be able to find it given some searching).
Hope this helps.

Quite unlikely, the AWS bands are licensed to TMO, im sure TMO would notice real quick if there were unlicensed cell towers on the AWS band and the FCC would be slapping ATT with fines pretty quick. quite alot of work goes into setting up cell towers and the frequencies each cell segment runs on, If a rouge cell tower went up overlapping TMO's frequencies, all hell would likely break loose as far as customers being able to get usable service in the area.
also as far as the terminology APN's don't operate on a "frequency" an APN is more or less and authentication/proxy server on the data network after the data has transferred over the air interface.
Maybe the best way to think of it is similar to a cell tower being like a wifi access point, and the APN being like an authenticating router/firewall on a standard tcp/ip network. yeah i know its not quite the same, but that might be a simple way to visualize it for those familiar with networking

Haha no, though i do have scanners and listen in on HAMs sometimes and have read up on the stuff somewhat. never gotten myself licensed.
On the subject of scanners, there isnt all that much interesting to listen too anymore. Here in tampa the police and sheriff are on analog trunked now, so its impossible to follow anything without a trunking scanner, and about the only other things you can listen to are cabbies, tow truck drivers, aircraft, and hams. I don't even know why scanners still have the 800mhz blocks anymore, analog amps cellular has been dead a few years now. you find lots of digital noise scanning around though, just about everything is transmitted digitally now. i've got an icom R20 that goes from 150khz all the way upto 3ghz
So why don't you put in an AT&T sim card with a 3G data plan and let us know if you get 3G on your HD2?

Thank you very much. I myself had been wondering why I couldn't get an HTC Desire (honestly, pretty much the only phone I'd change my HD2 for unless a GSM version of the Supersonic becomes available) and have it work in the US at the 2100 frequency.
When I asked before, people would tell me that a phone would have to support both bands (1700/2100) to actually run on T-Mobile because one did HSDPA and the other did HSUPA, but that didn't make sense to me since all you need is a single band frequency to handle both D and U data streams.
Your explanation makes a lot more sense. It's a sad thing, though.
I remember reading somewhere that a chip manufacturer (motorola?) was working on a all frequency chip. I also read that the inherent problem with that would be the antenna.
It would be awesome to have an all band phone that world travelers could utilize. I love the HD2, I had upgraded from a long time use of a Treo 750. That phone was pretty close (quad GSM, triple umts). However when Tmo rolled out it's 3G on 1700 I was still stuck on edge with the 750.
Finally bit the bullet for an HD2, really like this phone. The 750 seems antique now heheh

Building a multi frequency chip isnt all that hard. software defined radios have existed for quite some time. basically a simple reprogramming allows it to xmit/rec on a different frequency. the trouble comes in the antenna design. antennas must be designed to work at specific frequencies to be the most efficient at transmitting and the most sensitive at receiving. trying to make a single antenna capable of xmit and rec anywhere in a bandwidth ranging from 700mhz upto say the 2500mhz that wimax uses, is going to make for quite a ****ty antenna at any frequency. When you see the piece of foil antennas in todays phones, they may just look like a simple piece of foil, but a lot of design goes into them to make them work well at the frequencies they need to work with.
I guarantee if you compared the internal antenna of the Euro, AUS and USA HD2 there are slight differences. Ill bet the radio chip in them is for the most part identical, there may be something modified on them to keep people from interchanging the radio roms between them though since that would invalidate any FCC or other country equivalent certification for that phone to operate
Its one thing to run a hacked rom, its something completely different to use an uncertified radio rom. Could cause all kinds of havoc with the cellular network, and get slapped with FCC fines if they could track down your trouble causing phone

Yeah that's on par with what I had read, you do well at explaining it.
Maybe some futuristic worldphone designer would opt for interchangeable external antenna's... I could live with that or maybe multiple builtin foils with a software driven switch between them and the radio... that would be neat. Not holding my breath though...
Interesting on the FCC, hadn't thought of that.

Thanks, I was just again looking at the spec differences between the euro and TMO HD2s and i really don't know why HTC did not also give the TMO HD2 850/900mhz HSPA/WCDMA to truly make it a world 3G phone. According to the tech specs over at HTC.com, TMO HD2 can already use 850/900mhz for GSM/GPRS/EDGE so the antenna is obviously quite capable of both. The only other frequency the TMO HD2 has to handle that the euro doesn't is 1700mhz
Part of me thinks it was probably done so the HD2 couldn't be used over on AT&T

It had nothing to do with AT&T, it's because there's a difference between Edge and 3g radio frequency. More than that, there is no phone radio chip that supports all those frequencies and even more so, htc doesn't manufacture radio chips, they purchase them and put them in their phones....just like the majority of the hardware

I think this is incorrect -- the 2100 band support on the HD2 is in fact expressly intended for 3G compatibility in Europe/Asia, and people have reported being able to get 3G in Europe with their US HD2.
1700 == US-only 3G
2100 == Europe, Asia 3G
What's missing, I believe, might be 3G support in certain areas of places like Latin America which may follow US frequencies but don't have T-Mobile USA there to provide 1700 service... e.g., no 2100 and no 1700 either.
T-Mobile U.S. uses both AWS 1700mhz and 2100mhz for 3G. The 2100mhz band is used for transmit and 1700mhz is used for receive. Hence the incompatibility with other carriers phones that only operate in one spectrum.
Cheers.

Hi,
Seeing as most heroes including mine are on the GSM band of 900MHz and not the 850MHz that for some reason Telstra decided to use in rural areas, is it possible to flash another radio to 'unlock' (right word?) the 850MHz band to allow HSDPA speeds for me as opposed to the Edge network?
If this is possible, does anyone know where to get the radio for this?
TIA
hero doesn't have radio hardware, ain't it?

Sent from my HTC Hero using XDA App
its not possible, as the hero radio hardware itself is not capable of 850mhz umts/3g band.
Unfortunately, theres no way to simply 'unlock' it, as it doesnt exist.

So very wrong! Are you serious? You know there is more than one version of the Hero right? Euro, NAM, AU, and CDMA. NAM and AU have 850MHz UMTS.
What about the Telus or Telstra hero's? They use 850 in Canada and in Australia. Why would those carriers sell the Hero if it doesn't have the correct freq for their network? I have a Telus Hero and it has 850UMTS. Seriously, if you don't know the answer, don't say anything.
In my experience the best Radio file for good 850 Reception is the 09.26 radio. If you search you will find it.
Here it is...
I tried posting the radio file but it is too large for XDA. Sorry.
regarding to the HTC site the hero has those freqs:
Code:
Quad-band GSM/GPRS/EDGE:
*
850/900/1800/1900 MHz
and I think these should work with all radio versions.
http://www.htc.com/europe/product/hero/specification.html
but it does not have FM.
I forgot to mention that my Hero is not a native Australian Hero but a UK Hero which means the UMTS frequencies are: 900/2100 MHz.
Will flashing another radio give me 850/2100 MHz? (is the original question I should have asked) Telstra run 850MHz in Rural areas and 2100MHz in metro areas. Why on Earth can't Telcos all run on the same frequencies!?

No, it won't. The HW says 900/2100, SW won't change that.
Because they're douches. Mine is also the 900/2100, else I would've suggested a swap. :V

as has been made clear, he has an Australian Hero which only has 900/2100 3g bands. I probably should have stated I was assuming that when I posted my comment.
The Hero was never sold via carriers in Australia, only through electronic retailers, hence Telstra never actually sold the phone.
hi all
well, fianly after a big argument and debate with vodafail, about my ghg, and them saying that it will support ALL bands and freq's that they are supporting, or launching. i find out that, it will infact NOT support their 850 G network. which sh8ts me to tears. i have had nothing but trouble with them about this, and the constant reception dropouts that i am having.
i have flashed: radio 12.54.60.25_26.09.04.11_M2
and RIL_12.54.60.25_26.09.04.11_M2
but that hasnt seemed to help. so, i am wondering if there is a way to get my phone to support the aus 850mhz 3g network? is it a radio flash or anything? or is it a hardware based thing?
i looked around, but nothing is specific to my location.
i did however notice that the american version of the phone supports the 850 3g network.
so, is it possible to get it to work? or will i need another phone?

Wait, are you in Australia? As far as I know only Telstra uses the 850 MHz band. Vodafone uses the 900/2100 MHz bands.
yea. but vodafone are starting to roll out on the 850mhz for 3G. they havent fully done it yet, but my area is sposed to have it, and with all the constant drop outs that im facing, its BS. i have flashed a different radio to stock (listed in OP) and that hasnt made alot of difference. is there some way i can up the power or something?

I think you may need another handset my friend. It is a hardware issue.
Be thankful you are on not on WIND mobile in Canada! AWS and so few handset choices!

well, fianly after a big argument and debate with vodafail, about my ghg, and them saying that it will support ALL bands and freq's that they are supporting, or launching. i find out that, it will infact NOT support their 850 G network. which sh8ts me to tears. i have had nothing but trouble with them about this, and the constant reception dropouts that i am having.
i have flashed: radio 12.54.60.25_26.09.04.11_M2
and RIL_12.54.60.25_26.09.04.11_M2
but that hasnt seemed to help. so, i am wondering if there is a way to get my phone to support the aus 850mhz 3g network? is it a radio flash or anything? or is it a hardware based thing?
i looked around, but nothing is specific to my location.
i did however notice that the american version of the phone supports the 850 3g network.
so, is it possible to get it to work? or will i need another phone?
cheers

Worth trying the TELUS Rom Radio 23rd June 2011: Radio_12.56.60.25_26.10.04.03_M - Telus DHD 2.43.661.1 with matching RIL from Jkoljo thread. TELUS in Canada seems to operate on 850mhz for 3G. Hope that will solve your problem. If not... New phone I guess.
Cheers
You can flash every radio out there and it won't help. It is a hardware issue and not a software issue as mentioned above. The only Desire HDs that will have the 850 UMTS band is Telus of Canada or the Inspire from ATT in the US. I am surprised that Telstra does not have a NextG version.
Hmm I'm on Three which will be merging networks with voda at the end of the year.. apparently we'll be forced to switch sigh..
Hopefully it wont cause any problems, although, Three is only on 2100 and I currently have no issues with my reception (Three also uses Telstra's 850 network, but I'm guess I only pick up 2100 with my DHD).
I guess we'll have to wait and see. You would think that being able to pick up voda's 900mhz network would improve reception...
But yeah, as Agoattamer said, Voda and Three's DHDs wont work on UMTS850.
As per both Voda's and Three's websites, specs for the DHD:
GSM: 850/ 900/ 1800/ 1900
UMTS: 900/ 2100 HSDPA/ HSUP
So it looks like you'd need a new phone to make use of the new 850mhz network.
Hello,
I'm very sorry if the question was asked before, didn't dig to it.
If I buy a version GT-I9020 or GT-I9020T that works in 1700 Mhz UMTS rage will I'll be able to reflash it later to GT-I9020A to make it work on 850/1900?
I'm thinking about buying it but this is crucial for me, as I'm moving to a different country in a year and I need 850/1900 over there.
Thank you for you help!

Honestly I don't need a tip from Samsung. I'm asking you guys if I can flash different model band radio. I know that I9020T will not work with 850/1900 UMTS. I need AWS for now and 850/1900 for later.

That's quite impossible.
If you insist to try, then welcome your bricked phone
It sucks then. Any advice on the phone that will cover both 1700/2100 and 850/1900 UMTS bands?

buy a gsm galaxy nexus, it works on both sets of bands. other than that youre out of luck.
Thx, I've goodled it too. It looks like nice phone, but pretty expensive at the moment. I'll have to wait a bit a guest.
Verizon versions they sell on ebay are probably not flashable to pentaband?

You really, really, really, really need to do a lot of reading before you even dream of flashing anything.
Your question is analagous to asking if a software update will allow your microwave oven to run on gas.
A cellular phone contains a hardware radio that communicates with the network. Although people here and elsewhere often refer to a flashable "radio", what they really mean is a radio driver. Nothing you flash will ever change the hardware. Verizon and Sprint phones will remain CDMA (unless they also have a SIM slot, as a few do). GSM phones will remain GSM and will not be capable of changing their frequency via software.
