T-Mobile PPC-PE on Orange UK

Please tell me there is a way to get the T-Mobile version of the XDA (from Canada) to work on the Orange network in the UK! :roll: :?:
I have just bought one for my Dad (I already have an O2 XDA on Orange) and I've gone into the bootloader and selected radio 900/1800 which i believe is what orange runs on, but when I put my Sim into the device it just says no service
It's currently got RS 6.24.00 on the device, do I need to change this to 4.21.00 ?
If so how ? As I can't see the option in the bootloader to load/backup rom's like on mine
Please help
Cheers
Neil
Anyone ?
try to do a search i'm pretty sure that the gsm settings cant just be changed in software, and if thats the case then a US (900/1900) can never be used in EU (900/1800)
xda2 dont have that issues because it's triband (900/1800/1900)
Have tried searching already... couldn't find anything of relevance
There is the option in the bootloader that includes 1800, can't remember what the other exact options were as I don't have the phone with me atm. But I'm pretty sure the one I selected was 900/1800, so I hope (and pray) that this phone supports 1800.
Do I also need to select the band through WM2003 aswell as doing it in the bootloader?
Can someone confirm what band the UK networks Orange and Vodafone use, just to make sure I'm trying it with the right ones...
Any help much appreciated, as I'm getting desperate on this one, as its a crimbo present for my dad..
Cheers :wink:

EU as in all cellphone companies use 900/1800
it's the EU std like PAL is
US use 900/1900 and i dont think anybody else use that
did a quick search in the forum and came across this
http://xda-developers.com/phpBB/viewtopic.php?t=3064&highlight=900+1800
S**t S**t S**t thats not good
I've just been doing some searching on google and found that Cellnet and Vodafone use 900 & 1800, and Orange and One2One use 1800.
Does this mean I will be able to use Voda or Cellnet as they use 900.. and the phone is on 900 / 1900 ????
Cheers
Probably, just shove a voda or O2 card in and see what happens.
Thanks to everyone who helped, my Dad has now been given his PPC and it works on Voda

Is the carrier frequency reprogramable by firmware?

Dear hackers,
(I am new to this site, hello everybody)
a) Foreword: :arrow: I have a Wallaby bougth in the USA as SIEMENS SX56 (OEM PW10B1) and locked by AT&T. As USA GSM uses 1900MHz and now i am in Brazil which uses 1800MHz datacarrier frequency.
b) :?: Therefore the question: Is it worth trying to unlock the phone to use it here? I mean, the phone may be unlocked but then, is the carrier frequency reprogramable by firmware or simply configurable by software? :?:
Thank you in advance for your reply :wink: .
Bye,
Juan Carlos :idea:.
Look at the rear of your xda, if it is 10B1 it is 900/1900 if it is 10A1 it is 900/1800. This cannot altered as far as I know.

Please Help, bought SX56 (UNLOCKED) Won't work on Cingular network

I bought an SX56 Unlocked and i can't get it to work on the cingular network. Its really frustrating. I called Cingular and tried to get them to update my IMEI and they couldnt do it because they said the phone originated from AT&T, but they also told me that it should still work on the network even though they can't update the IMEI! I have tried switching to all different GSM bands and nothing is working. PLEASE HELP! There has got to be a way to fix this!
-Praetorin
i can fix it for you!
$$
How
? How can you fix it? Do you know how to make it operate in 850mhz gsm?
Is there a way to change that?

SX56
This is funny question!
SX56 is GSM 900 / 1900 only.
Freacking Cingular works with GSM 850.
So... what do you think?
