I have a 1.0.1 (1C25) iPhone and I don't know how but it has been made to work in the UK tho it was bought in the USA. I don't know my bootloader either but I want to get 1.1.1 or over on the phone. If I just press restore in iTunes, will that brick it, will it be completely restored to its AT&T netowrk restriction? or will it be an un-jailbroken phone that can work in the UK? As I said I don't know how it was made to work with any sim. Is there a way to find out how my phone was made to work with a UK sim cos i NEED to upgrade, 1.0.1 (1C25) is annoying me soooooo much!
