I have an Iphone factory unlocked (bought in Italy) and also Jailbroken afterwards and while in US I'd like to use a prepaid card from ATT.
I bought a pay as you go phone at ATT and when trying to use the SIM card on the Iphone I get no service at all!!
Any idea what is the problem?
I'm running on a 3G Iphone 3.0 OS, with jailbrake.
Is that the problem - jailbrake, or ATT does not allow prepaid customers to use Iphone?
I really need some help to solve that!
