No, I am trying to "unlock" my iphone (currently locked with AT&T carrier), so i can use it with other carriers. I am out of AT&T contract already, and they have sent me the unlocking instructions. The steps in the instruction are:
My question is, is it NECESSARY to "erase the contents" (step 3), in order to unlock the iphone successfully?
Thanx... Trumania and Meg St._Clair!
But, I am confused about step 4. It says "Swap the old SIM card with the one for the new carrier".
Does it mean if I do a "restore from backup" with my existing AT&T sim (not with a new carrier sim, as I dont have it yet), the unlock wont be successful?
