Hi, just got a iPhone 1G, (1.1.4 i think) and I had AT&T. I switched to Rogers and got the sim card. I updated my iPhone to 3.0.1 and I can't verify my iPhone because I switched to Rogers. I Tried using my AT&T sim card but AT&T doesn't have me registered so I can't verify it. Also tried my Rogers sim card , but it says the SIM card is not supported by the iPhone. Please help me, Thanks. PS: my iphone is not jailbroken.
