    i just got a iphone from my friend. He had it jailbroken and unlocked with a t-mobile sim card. I used to have a vu for at&t but i took the simcard out and slid it into the iphone and it worked. the internet and everything .

    I'm thinking you may need a new SIM card. Take it to an at&t store and have them try a new one. Sounds weird that it worked when the phone was unlocked, maybe that allowed for a wider range of SIM card models?

    My iPhone couldn't access the cellular network with a "pay as you go" phone SIM. I took it down to an at&t store and swapped it out, that did the trick.
