Hi, i was considering downgrading my 7100t in the UK, or simply re-installing the firmware again, i was wondering if anyone has a link for the actual firmware (its a retail version, not exchange enabled). And i have just unlocked the phone using my data cable and some guys software from ebay (for which you have to buy credits), which was done by entering an MEPD2 code or something, if i remove the OS, or upgrade/downgrade, will it affect the unlock status, i.e. will i need to unlock it again. (I unlocked the network settings, the sim lock was already unlocked.)

Cheers

No it will not lock the phone again. Here's the download page link http://software.se.t-mobile.com/

Thanks for the info, I knew of that site but is it the same for the UK version of the handheld software, becuase i have used the link found in the thread called 'noob: T-mobile UK handles OS4.0?'
