I have an iPhone 4 which is att and I want to do gophone, buy a sim gophone a cell and insert it when I said that the sim card is invalid and is not to be due to that. please help I do?
well your going to need to jailbreak and unlock first because when an iPhone is ties to ATT i think that is just the post paid plans
the phone is probably jailbroken, but not unlocked from the sound of it.
My iPhone 4 is on 3.10.01 modem firmware (which is not unlockable) yet my GoPhone SIM works just fine.
No unlock needed!
Do people just guess without actually knowing what they are talking about when they provide information to others? Is this the iclarified official forum?
I also think you may have cut your SIM incorrectly to fit the phone (but that should result in a no sim message) or that SIM is already bonded to another phone (was used to activate another phone for service.)
