How to activate iPhone 3gs 3.1.3
Hi! I just bought an iPhone 3gs from ebay and it came with 3.1.3 firmware and 5.12 baseband, and when i turned it on its in the please insert a valid sim card screen... From what I understand is not possible to hacktivate the phone, nor unlock or jaiolbreake, the only solution is to activate it with an ATT sim card.
If I manage to get an old att sim card (not activated right now) or a Pay as you Go sim card, will I be able to activate it???
If so, please tell me wich are the steps.
Thanks a lot,
