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!

Could you share the service manual if it is alright?
What is the difference between the two and can you make an "a" an "i"?
the differences are the 3g frequencies that they support
i forgot the exact bands but i know that the x10a supports us atnt, rogers canada, and telstra australia 3g bands. the x10i supports asia and european 3g bands
The difference is pronouncation. Also a is the first letter in the alphabet while i is the 9th. I don't think you can make i into a and vice versa.
PS. You can make [email protected] and vice versa but it causes SEUS problems.
x10i and x10a both have the same GSM network frequency as 850/900/1800/1900, or you can call as as Edge network as well. As for the 3G frequency or UMTS bandwidth, here is the difference:
x10i
UMTS: 900/1700/2100 MHz
it will support Asia / Europe / and T-Mobile USA 3G network.
X10a
UMTS: 800/850/1900/2100 MHz
like dorifuto.boi said, it will support AT&T US, Roger Canada, Teltra Australia. It also support Japanese Do-co-mo 3G network as well.
You may wanna check with your current service provider and ask them which UMTS bandwidth they fall into the above category. Again, this is for GSM network only. If you are using Sprint, Verizon, etc they are in differenet as they are in CDMA network.
To further add to your comments
SE uses the a or I for country variants
A - America's (Canada, US & Latin America) Support these bands
I - International (Europe, Asia, Middle east etc) support these bands
thanks for the info. I received and "a" as a gift, but am not able to get on tmobile3g. Only getting edge, but it runs fine.

Bell and Telus have 3G (only) networks in Canada in these bands
By the way... it is technically possible to build a phone that works on all the 3G bands, so that it would not be required an "a" and an "i" version?
the Nokia n8 is like that. 5 band 3g. but the x10 is not

Yes it is - for some weird reason t-mobile was included in the international version, and AT&T was on the American version... But the facts is, that both versions have 2100 MHz 3G which is the most used 3G band worldwide... As I see it, you will just have to go into a secret menu and then check off some other boxes, and then it should be able to use the other 3G bands!
I'll post an image...
Uploaded with ImageShack.us
just because they both have 2100 doesn't mean ATT and t-mobile are using them. personally they should have made 1 model with quad band 3g. better for everyone.

Hey guys,
Looking at pre-ordering the unlocked version of the DVP from Clove but I'm not sure whether it is going to work in Canada =/.
I've looked at all the Canadian cell phone providers (Telus, Fido, Bell, Rogers) and it doesn't seem like they are compatible with the 3G band on the Dell Venue Pro (900/2100).
Canadian providers seem to require 850/1900 or 1700.
So uh...is it worth buying the phone? Anyone think it will work?
Does the phone need to be 3G compatible to work? (Telus seems to say that your phone NEEDS to be 3G+ compatible).
Thanks,
-Sean

is 3G necessary for smartphones?
I've never had a smartphone before. right now I'm just using an old flip phone.
Would the phone need to have 3G in order for me to bring it to a carrier and add a sim card + plan?

Yea, 3G would be pretty much a necessity, as the next best available connection you would get is edge, which is much slower.
For $989 this site claims to have a Telstra NextG compatible version up for grabs:
http://www.mobicity.com.au/dell-venue-pro.html
I have been using a Telstra HD2 on Telus which gives me 3G+ for a while so I would assume this one would also work. But then again I could be wrong as the bands don't look right..
So it does work if i only use for 2G cell phone service with Fido (no internet), right?
I can use WIFI only.

no your wroung,
you need 850/1900 UMTS/HSPA if you want to use rogers, fido, bell, telus, virgin, koodo, on 3g
you need 850/1900 GSM if you want to use rogers/fido with no 3g
if you want to use wind mobile you need 1700/2100 UMTS/HSPA (same as t-mobile)

There's that 1700/2100 that I need!
Yay!
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)?

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.
Regards,
Dave
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
Hi guys,
I picked up an SGSII from Expansys and it runs no problem on Fido up in Canada. I'm taking a trip down to the US next month and was wondering which of the big carriers in the states would run the SGSII. I figure AT&T would, but as the phone is quad-band, I'm not 100% sure if there are other national carriers that would do the trick.
Thanks!

Of the major US carriers, it will work on ATT and T-Mobile. It will only get 3g on AT&T as the SGS2 doesn't support TMO's 3g bands.
Hmm. I'm a little confused. The wikipedia page for T-Mobile says that their 3G bands are 2100MHz and 1700MHz. The SGSII apparently has 2100MHz as one of the accepted frequencies (again according to wiki). How come 3G won't work on T-Mobile?
Presumably, the phone won't work on Verizon because, while the frequencies match, Verizon is running on CDMA and the SGSII only supports GSM. Right?
Thanks again!

T-Mo US needs 1700 and 2100, not just 2100. Att uses 850 or 1900. 3G won't work on T-Mo
No matter what it says on paper, there's a couple of people here that have tried the phone on T-Mobile U.S and get EDGE speed downloads.
Good stuff. Thanks for the help guys.
