US vs. UK Dream - Hardware difference?

Does anyone know if the hardware is different from the US G1 to the UK G1? I know the US model uses the 1700 and 2100 bands for 3G, while the UK model uses 2100 only. Is this due to a physically different radio chipset, or is it strictly a ROM change? Could one flash a US ROM onto a UK G1; and would it work on 3G in the US?
Thanks in advance!

I'd expect the 3g radio/chipset would be the same in them. If you take your UK G1 to the US I would imagine it would work on the US 3g network fine.

There is a hardware difference, extra antenna/amp chip. The T-mobile network in the US uses both 1700 and 2100 bands to establish the 3G voice/data connection. You'll be able to get 2g for sure, but not 3g. T-mobile uses 1700 band for up and 2100 for down stream.

Do you have a pic of the motherboard or some other evidence of this?

I think when the op said the Dream uses 1700 and 2100, he meant UMTS Bands IV and I respectively. The Dream communicates with T-Mobile USA using only Band IV, which is commonly known as UMTS 1700, even though it does use 2110-2155Mhz for the downlink. More info here.

All the USA T-Mobile APNs are installed on the UK version, are there any 1700 ones listed?
I deleted them all or I'd check myself.

I have both the US and UK versions of the G1 in hand. I have looked at the list of US APNs, but I'm not really sure what to look for. They all specify epc.tmobile.com, but beyond that the numbers don't mean anything to me. Can someone tell me what to look for?
As far as the radio chipset, I have the service manual and I'm willing to disassemble the UK G1, just not sure what to look for. I'll be glad to take pictures along the way.
Externally, I have found a few differences in what's printed under the battery-
US model: DREA100
UK model: DREA110
US P/N: 99HEW038-00
UK P/N: 99HEW042-00
Of course, the difference in numbers could lie in the firmware.
Thanks everyone for the input thus far, any other advice you can offer is also appreciated!

Rogers Magic On Tmobile??

i just purchased a rogers magic due to the 288Mb ram, so that i could smoothly run the hero rom. However i have tmobile and after doing some research it seems that i wont be able to use 3g because of the frequencies.
So can anyone comfirm if this is true as i need or rather want 3g to work on my rogers which is yet to arrive..

Rogers Magic supports.
GSM/GPRS/EDGE Bands: 850/900/1800/1900 MHz
HSPA/UMTS Dual-Band: 850/1900 MHz
So I don't think so, I believe T-mo only supports 1700.
Clinton

guess i will have to sell it! as i need to have 3g working. But one more thing is is ther any magic phone out there that has the 288mb ram and supports tmobile 3g networks????

T-Mobile USA seems to be the only major carrier that I can find that uses a hybrid 1700/2100 HSPA setup. So, unfortunately, I highly doubt you will find one. Only way I can see it happening is disassembling two units and swapping radios.

I want an htc magic (Rogers)

I hope this not a problem posting this here. I am from Delaware and I am trying to get rid of my iPhone 3gs and get an htc magic with AT&T 3g bands. I am having no success with craigslist, it is flooded with iPhones. If anyone out there has a htc magic in great condition with warranty and wants a iPhone 3gs with a full zagg invisishield already on the phone. Please contact me at
[email protected]

Won't happen.
The Roger's Magic isn't going to put out the 3G capability you're looking for on the AT&T frequencies.
It would have to be properly scaled and designed to function on those frequencies, which it isn't. If a phone is GSM, that doesn't necessarily mean it can output the 3G speeds on any GSM provider. The MHz bandwidths need to be the same.

htc magic at&t 3g
Can anyone else confirm this, I have read multiple forums that have said that it is possible. The specs for Rogers say UMTS 850,1900 which is the same 3g freq. that AT&T uses.

It works with Rogers HTC Magic
I can confirm 3G works on AT&T with the Rogers HTC Magic.

Rogers uses the same bandwidths that ATT uses.
This is for the reason that Rogers used to be Rogers ATT.
I can confirm that my HTC Magic from Rogers gets 3g.

T-Mobile G1 with Rogers HTC Dream radio

Hi everyone,
I bought my T-Mobile G1 from the states about a year ago, when the G1 was exclusive to T-Mobile. I am currently using my G1 on the Rogers network. I knew I would only get EDGE and won't be able to get 3G on my phone but I was content, because I wanted the G1 so bad!!!!!! Rogers operate on 850/1900Mhz and the T-Mo G1 runs on 1700/2100Mhz. Now since Rogers are selling the HTC Dream, it changes things for me. I want 3G!!!!!!
So, to get down to the point, I was wondering if there is a way for me to flash my T-Mo G1 with the Rogers HTC Dream image/firmware/radio so I can get 3G on the Rogers network?
My G1 info:
DREA100 PVT 32B
HSPL10.95.3000
CPLD-4
RADIO-2.22.19.26I
I know there are a few posts about this, but all the posts died.
If there is a existing post about this inquiry please point me to the right thread.
Thanks

good dream!
its impossible unless u replace the hardware

I'm fairly sure that's a hardware limitation, and not something that software can fix. People have tried flashing the Rogers radio on tmo dreams and ended up with bricks (shockingly >.>).

i need to flash an htc g1,
and i dont get any software to do,
the matter is that it is resetting,
i already hard reset it, and its the same,
what do you sugest?

I think this is very possible. I have in my possession a G1 from T-Mobile UK which was reflashed with the US ROM and it works swimmingly on 3G here.
Correct me if I'm wrong, but T-Mo UK's 3G is on 1900 MHz and US is on 1700. This would lead me to believe that the radio IS capable of operating on all current UMTS frequencies.

Sorry fine sirs,
but you would have to find a Canadian frequency version of this and install it in your phone.

i need the 1900mhz rom, urgent, help me please,
as i know here in this forum theres many smart guys that know about this,
here they can help, do it please
thank you in advance

Why don't you just try it and find out? If it doesn't work, then just flash back your original image.
I don't think you need to change the antenna. The radio chipset is what determines which frequencies you can operate on, the antenna is basically a glorified piece of wire. Think about this: the G1 in the USA operates GSM/GPRS on 850, 900, and 1900 MHz, as well as UMTS on 1700 and 2100 MHz... all with the same antenna! You don't need to change it to operate on Rogers.

Really? Then why has nobody successfully "converted" the antenna to other frequencies?

Dude go back and read my last two posts... I have "converted" a UK G1 (read: no 1700 MHz band in the UK) to work on T-Mobile USA's 3G. The only "conversion" I did was installing the US ROM. No antenna swap, no mainboard swap, did not open the phone whatsoever. Unlocked and the flashed. Done.

So you didn't get 3G before, and after flashing a "US" ROM (ROMs are region defined?) you have 3G? Hmmm

No, that is not what I said. When I received the phone, which was a UK model with the T-Mo UK ROM installed, I immediately unlocked it, rooted it, and reflashed with the US ROM. I did not test it before hand to see if 3G worked because the phone was locked to T-Mo UK and I only have a T-Mo US SIM card. I never said that it was not capable of 1700 MHz before the flash, only that the hardware was capable regardless of where it was bought.
And yes, the T-Mo UK ROM is different than that of the T-Mo US ROM. I am not a programmer, so I do not know how fundamentally different it is, but it most definitely comes with different apps and customizations, as well as APNs. Also, if you remove the battery cover, the UK model has a different part number than the US model. Beyond that, it is shown as an 'unrecognized device' in T-Mobile USA's system, whereas the US model shows up as an HTC G1. I believe that this is only related to the ESN, but the internet only works on it with the Android data package- it would not work on the Sidekick plan. I don't know if it's network-side or phone-side, but something is identifying it as an Android device.
Anyway, my whole point to the OP was that his phone should have the proper HARDWARE to operate on either Rogers' or T-Mobile's 3G, and that if something was preventing him from doing that now it was most likely due to the software on his phone.

The only part of a ROM that could change this would be the radio

That's the Rogers download page, try it out.

Bump: anyone try this out yet? I'm curious... It seems hard to find the Rogers standalone update though, you might need to unroot then reroot to do this.

3G ATT (usa)?

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

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.
