I have an option of getting a turbosim from hong kong, since they are in plentiful supply there. However they all unlock US AT&T phones there, whereas I have a UK O2 iphone. With regards to the turbosims and files you need to jailbreak/activate the iphones, and the files needed to program the turbosim is there any difference between the US and UK iphone versions? They are very adept at unlocking US iphones with 1.1.2 OTB, but they don't know if they can do it for a UK iphone, and I don't want to risk messing it up. Thanks.
