Hello! Ive allready downgraded a 1.1.2 european iPhone to 1.1.1 and Jailbroken it. Now, ive heared that if i downgrade again but this time to 1.0.2 i will be able to use any o2 2G sim in it. If i use iTunes and the Alt+Update method, will my phone get bricked while downgrading? (1.1.1 > 1.0.2) Could someone please confirm this before i attempt it?
