hi there
Actually i am running on iphone 3G and its locked to rogers but i unlocked it via sim adapter
anyway every time i connect my fone to the itunes it recognizes that the sim card inserted is not supported and bla bla bla so i MUST remove the sim card
i asked before about that and the solution was to jailbreak it and activate it but i didnt find a check box in the quickpwn called sim card provider
iClarified - iPhone - How to Jailbreak Your 2.1 3G iPhone Using QuickPwn (Windows) here it is a link
thx alot in advance
