I've got a 4S which is obviously not jailbroken and I'd like to change the carrier name. I know that there used to be a plist hack but I tried that and it no longer works. I have been looking around however, and noticed people saying that restoring from a backup that had makeitmine or FakeCarrier installed kept the changed carrier name. So here's my question: If I jailbreak my old 3GS and change the carrier name then restore the backup to my 4S, will the carrier name revert to default or would I keep the custom one? The only thing stopping me from testing this is that my 3GS is now in use by my Father and I don't particularly want to inconvenience him unless I know it would work. Cheers!
