US vs. UK Dream - Hardware difference? - G1 General

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!

January 22nd North American 850MHz HSPA 3G Blackstone...

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.

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...

T-mobile's US HD2 works on 2100 MHz 3G in Europe?

Hi,
The official specs of T-mobile's HD2 says that the supported 3G bands are: WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz
Does it mean it will work on European 2100 MHz 3G too? Nexus one does so I suspect HD2 could too but as far as I could digg nobody had a straight answer to this question yet.
-AlefSin
actually i asked HTC CS before, and the answer is NO!
european countries WCDMA frequencies are the same with ASIAN countries. So no chance for European countries either.
hmmm I don't know JohnQ. In your attached email HTC is saying China's frequencies are different from the rest of the world so how do you say it's the same as Europe? I don't know much about 3G network in China though.
Just a few weeks back it was annoounced that the US operators had all signed up to migrating to the rest of the wold's GSM standards!
So in time we will all be singing from the same hymn sheet!
Accoridng to Wikipedia, while 3G in China is using the same frequencies as Europe in UMTS-I band, the air interface is different (TD-SCDMA vs TD-CDMA).
(sorry, cannot link to the docs since as junior member cannot embed links yet).

Wow, that's... odd! It seems US operators cannot even agree whinin US and now they all want to use the rest of world's standards! That's so un-american!
At&T, rogers, etc are all using european 3G frequencies, which is why you can use device from europe on their networks.
T-mobile US uses 1700 & 2100 (one for up stream, one for downstream) which is why it won't work on at&t etc or european frequencies.
The t-mobile 3G phones use both 1700 and 2100 at the same time; and they cant use 2100 seperately on other networks.
erm att uses 850/1900,and very few operators use the same,none in Europe use these bands

Well, it seems the answer is negative. I asked HTC:
Hi, I'm very excited about HTC HD2 on T-Mobile USA. However there is a cruicial question taht I could not find an answer for yet: Should I get this phone, when I travel to Europe, can I use 3G? The specs say this phone will support AWS/2100 MHz UMTS. Since the 2100 MHz is the dominant frequency for western european 3G networks, does it mean this phone would work on their 3G networks? Nobody at T-mobile's support could answer me so I hope you could solve this mystery.

And they answered:
Thank you for contacting HTC Technical Assistance Center. I understand the importance in researching a phone before you purchase it. This is a unusual situation and one T-mobile may not have been experienced with. For T-mobiles network the phone will be using the 1700 and 2100 bands. Although the 2100 band is common world wide. allowing the phone to pick up the edge network. T-mobile uses the 1700 for there 3G services. This band as far as we are aware is only used by T-mobile when it comes to major carriers world wide. More then likely the phone would not be able to pick up 3g if taken over seas.
However. T-mobile dose have a few branches in Europe. You may wish to check with them to see what bands they use for 3G, and if they have had any conflicts with American phones.

But T-mobile's HD2 is not out yet! Are you sure you didn't test European HD2?
OK things are starting to get weird. I received a negative answer from HTC's customer support but then I found USA T-mobile G1 users that reported their phones were working on 2100 MHz 3G in Europe (G1 like US T-mobile version of HD2 only supports 1700/2100 MHz 3G). I need to buy a phone and these contradictory reports leave me confused
Here is what T-mobile says in the specs sheet of the new HD2:
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100)

I tested my unlocked TMOUS HD2 in Sweden using 3's network and worked like a charm in 3G
Bit of a bump here as I'm trying to use my unlocked US T-Mobile HD2 with Orange in France and I can't do better than Edge (it went down to GPRS at one point...). I guess it could come down to spotty reception but I do get 3G speeds in my current location with an iPhone 3GS so I'm not so sure...
I'm using the AmericanAndroid ROM, maybe that's why my speed is throttled ;-)
I am using HD2 T-mobile in Serbia and i have no problem with conection or data speed.
I was on vacation and i didnt use Wifi ,and i used the phone all the time on 3G - the 3G network is incredibly fast, I even think that it is twice as fast as the EU HD2, which I used before..
Thanks, will check again then, maybe bad reception then!

T8185= EU, T9193 = AUS, which model is available in Asia?

I'm just a little bit confused. read up on a bunch of posts here that talks about the different models there are right now..
from what i've gathered
US t mobile = pretty much T8185 but with 1gh rom
EU = T8185
AU = t9193 with 850 band frequency coverage
so which version do retailers in asia carry?
thanks all.
cheers.
ok..I want to correct you...in europe the HTC HD2 is T8585
t8585 model
thanks for the help!
Determine Model of Phone?
I just received my HD2 from an internet retailer, and 3g doesn't work with T-mobile US.
In band selection it has 900 and 2100 as UMTS options and no mention of 1700.
How do I determine exactly which model I have in my possession? I'd like to have all the facts before I ***** these guys out and demand a new and correct phone.
I tried to check the radio and rom versions, but I couldn't see way to tell the versions apart.
ROM 2.10.531.1 (82076) WWE
Radio 2.08.50.08_2
Ram size 576mb
If you want a phone that is compatible with TMobile in the US, you need to buy it from... drumroll... TMobile in the US. No one else is compatible on their 3G net.
The TMoUS will have TMobile right across the top of the screen.
The 9193 will have NextG and "T" on the lower third of the back case.
The 8585 will be completely unbranded, as far as I know?
I'm living in Singapore, bought mine from starhub,
The model is T8585 and supports all frequencies [HSPA/WCDMA/GSM/GPRS/EDGE (900/2100/850/900/1800/1900 MHz)] , so it'll work everywhere

You only have 3g on 900 and 2100 with that model, though. All the models have gsm working on all the bands, so you can get regular service everywhere.

Thanks for the info mazzarin,
Somehow 3g started working.... maybe I just needed to leave the house. 3g was showing in the status bar before, but failing to connect. My phone says T-mobile across the top, and the UPC on the box seems to be a US phone; however, under settings-->wireless control-->phone-->Band it still lists UMTS (2100+900 as an option), which doesn't make sense.
Any idea what this means?

The Telstra 850+2100 phones say the same thing. Just ignore it. The bands are determined by the hardware amplifier circuits on the phone anyway. You have the TMOUS HD2, so you are fine. (Other than their tiny network )
The network may be tiny, but 2mb/s down and 1 up is pretty good. Coming from AT&T service, I'm impressed with the speed. Now I can't just leave any major city

US T-Mobile's 3G freq vs the rest of the world?

Anyone getting the T-Mobile version tomorrow? With CDMA not SIM capable, and AT&T version still up in the air, I think I'm probably going to get one tomorrow!
I've got question regarding T-Mobile's werid 3G band tho. I think Samsung listed T-Mobile's version as AWS 1700/2100. I know 1700 is weird, but is that AWS 2100 same as the 2100 band that the rest of the world use? Sorry it's my first 3G T-mobile device, and looking on wiki or google is just kinda vague
2100MHz is the band used all across Europe as well as large parts of Asia.
So, yes, the T-Mobile one should give you 3G capability in other parts of the world, though if it's locked that may open up other issues.

I had a TMo US G1, and it worked fine on 3G when I returned to the UK. The converse was not true of my TMo UK G2 (HTC Hero), which would only get Edge in the US because it did not support both bands of AWS (1700/2100).
So, I see no reason why a TMo US shouldn't work pretty much everywhere else in the world where 2100 3G is ubiquitous.
Regards,
Dave
Cool thanks, i guess that AWS threw me off. I thought there were a regular 2100, and then T-Mobile's AWS 2100

Actually you're a bit off. Tmo's 3G runs on AWS 1700/2100 band which is not the same 2100 *frequency* as the rest of the world. Tmo uses 1700 for downloads and 2100 for uploads, so both bands (aws/band IV) are needed.
Now Europe (and rest of GSM world) use straight 2100 band for 3G but the exact frequency is not the same as Tmo's.
Basically a Tmo Galaxy Tab will only get you EDGE outside of the US. An ATT Galaxy Tab will get you 3G in the US and the rest of the world (as long as it's sim unlocked, ofcourse).

No, the T-mobile phones give you also 3G in Europe. All AWS chipsets do both Band I (2100) and Band IV (AWS 1700/2100).
I thought the galaxy tab is quad band, so you can simply swap your sim card with another european carrier and it should work on thier frequency
Am I wrong?

You're right for 2G, not for 3G
So getting the unlock code for tmobile device and putting AT&T sim card will not give me 3g connectivity (using AT&T network)?

No, the T-mobile phones give you also 3G in Europe. All AWS chipsets do both Band I (2100) and Band IV (AWS 1700/2100).

It will not. Pls do some more reading on the subject. There's a very good writeup on it in these forum. Someone explained it better than I've probably done. If I find it I'll link to it.

One could say the same to you.
This is a link to T-Mobile US's support forum, in which someone has had it confirmed from T-Mobile themselves that all devices designed for their network have to be fully compatible with the 2100MHz band, meaning they will give you 3G capabilities in Europe.
Your previous post in which you claim that the 2100MHz band that T-Mobile use is not the same as the 2100MHz band the rest of the world uses is nothing short of ridiculous.
If the band T-Mobile used was different to the one used in the rest of the world, it would not be described as 2100MHz.

Sorry, but as I already said earlier in this thread, my T-Mobile US G1, which is an AWS device, worked perfectly well in the UK with full 3G. Similarly, I know of people who bought TMo Nexus Ones in the US, and these all worked fine in the UK.
That's not to say there isn't some subtle difference which not all chipsets can cater for, but it is certainly true that many TMo US handsets will give 3G capabilities in Europe.

The normal UMTS 2100 is called "Band I" and t-mobile's AWS is called "Band IV":
http://en.wikipedia.org/wiki/UMTS_frequency_bands
The AWS 3G module has already 2100MHz support, so there is no additional hardware necessary to support Band I as well. Theoretically it could be disabled, of course, but then T-mobile wouldn't be able to charge you an arm and a leg if you were to roam outside of the US

DVP 3G Europe/US Roaming

If I understood right at least some DVPs have radios capable of using both T-Mobile US's 3G network and European 3G networks. Has anyone tried this? Are we sure that all DVPs have the same radios? Or do the European ones have the US frequencies disabled or something?
Thanks in advance for any info,
Tom
The US ones have AWS for TMOUS, and European 900/2100.
Whether they will actually provision correctly and be usable w/ 3G services in non-US locales is anyone's guess. The US DVP has only just recently been unlockable and I don't think we have had any reports of actual int'l roaming success yet.
I think its been mentioned in the unlocking thread that people have used it in Europe and from the listing of the DVP I've seen the specs indicate its has the exact frequencies as the US one. I would expect it to work, unless Dell has done something really screwy (but thats not impossible) but hopefully someone can confirm for sure.
People are claiming that European DVPs have AWS 3G support? I don't think so.
Although it is conceivable that it's there and simply unadvertised, I believe non-US DVPs have 900/2100 *only*.
US DVPs have 900/2100 *and* AWS.

Actually I was referring to people with US handsets being used in Europe, not the other way round. And its possible the Euro version is hte same as the US one, looking at a video of a DVP released in India it shows the same frequencies as the US one, and Clove also lists the same 3G frequencies so I would lean towards all DVP's bring usable in Europe and the US.
With today's big news, what's the point?
Once AT&T shuts off AWS UMTS in a year or so we are all gonna be left with paperweights anyway.

NAY, I SAY THEE NAY!!!!!!!! Could be right though, but I was planning on ditching the DVP for a penta band Nokia so I guess I'll be ok - save for being on at&t!
3G works here
They are saying it will take "several years" to transition T-Mobile users. Lets hope the regulators see sense and block it in any case...
So I have a European DVP now. Anyone know of an app that will tell me the radio frequencies it supports? The System Info one doesn't seem to.
It supports 900 and 2100.
How did you find that out? The box says UMTS 2100/1700/900.
The European box says the phone inside supports 1700?
my US T-mobile DVP (unlocked) works fine on tmobile Germany and I get about 3000k download 2500k upload. I am in a fairly bad region for network speeds. But I have hit upwards of 7000k download in some bigger cities.
