...Use my iPhone with an O2 Pay&Go sim card. I have hacked my iphone so i can do this but what i have been trying to find out is... ...Can i ever upgrade past 1.1.2? I don't care about any of the apps available through jailbreaking my iphone, i only use SummerBoard so i can have a background but i could live without it. I would love to be able to update without worrying about having to activate my phone again! I simply cannot afford the tarrif that O2 have set out for official iphone use! Sp what i ask is, has anyone who has 'hack-tivated' their iphone only to use an O2 sim other than the official iphone tarrif, upgraded and not been asked to re-activate thier iphone? Can anyone answer?
