go to the soney ericcson website and get there firmware update
get a serial or usb cable as b-tooth wont work for connecting
then follow the instructions
you will then have a fully unlocked unbranded phone well ulness its a orange branded one as they got logos
all over the case lol
the markets charge upto 10 quid just to do that for ya
you can get a cable for 2-4 quid and the software is free
