All T-Mobile HD2s the same?

[redoano]

Hi everyone!

i'd ask a question important for me : I will buy a HD2 but u know there are two versions of it. U.S. T-Mobile ones are better in ram and rom. But are all the T-Mobile ones the same in hardware? May i trust to buy if it has "T-Mobile" logo on it?

I'm the owner of a T-Mobile branded HD2 but not the T-Mobile US version.
As far as I know only T-Mobile US version has the T-Mobile logo on top and red and green buttons on bottom.

See my post on this topic: http://forum.xda-developers.com/showpost.php?p=16683539&postcount=9
plain text:
Just to complete the list: there are more versions of the HD2 than two and memory isn't the only difference.

1. T-Mobile US PB81120 (more memory for T-Mobile requirements and for USA specialized radio chipset)
2. European HD2 PB81100 or T8585 (specialized radio chipset for Europe)
3. Asia/Pacific HD2 PB81110 or T9193 (specialized radio chipset for Asia/Pacific)
4. Chinese HD2 T9188 aka Tianxi (with specialized radio chipset for China and design adjustments)
5. Dopod HD2 T8588 (identical to T8585 apart from dopod logo)

EDIT: my advise: to use the full potential of a HD2 in Europe I would like to recommend a European HD2 T8585 because of the used radio chipsets for data transfer.

Thanks for your info. I didn't know about these differences. Then i have another question : Is t-mobile u.s. version much faster than europe hd2 version? It has more ram than europe and so it is faster but can we see that difference while using phone for exlaying games etc..?

I can't say if it's really faster, because I haven't seen a T-Mobile US HD2 live.
Maybe there is a review on youtube...
I'm not unhappy with my HD2's speed.

RAM can be equal on all HD2 models via supporting ROM & radio version. US T-Mo has 1GB of ROM which is a big bonus.
Main concern is radio bands are different also a third Telstra model can be thrown into the varient equasion in this respect.

Speed is important for me so u.s. version seems closer to me although i am in europe. My another question is : What varies when radio bands are different? What kind of problem may occur because of this variety? Does anyone know?

 

[uli71]

3G/UMTS radio frequencies used in USA are different to frequencies used in Europe.
Therefore the radio chipset is different.
Problem: GPRS data transfer speed (114kbit/s) instead of 3G/UMTS data transfer speed (7,2Mbit/s) if you use a T-Mobile US model in Europe.

Don't let me be missunderstood, this is not a general problem.
It depends on the network operator and which technique is used in various areas if this problem occures.
Who can say which network operator is using which technique in which area? Perhaps there is a problem.

I own the US T-Mo & have yet to have any issue with 3G on any provider I have used in UK Europe & Asia Pacific.
As for performance at gaming they will all be the same but with the larger ROM storage you can install more softwares directly to your device.
If you are a gamer I assume you will be going Android ! so if that is the case you would probably be best getting a dedicated android device that is newer in terms of hardware & doesn't suffer from some of the Android HD2 porting issues ...

Woouww that is a big big bigg problem if true.. I use up to 7.2 mbps and i cant bear slow internet So i'm afraid i will have to buy europe version if that problem is true..

Mister B; What is your internet speed with t-mobile version in Europe? And of course i am going to be going android because I already fed up with winmo 6.5 while using touch HD So u say gaming performance the same in two versions, only rom may be problem. i think rom is not a problem if ram isn't Thanks..
