Long long story really short 1. Bought an iPhone 5 launch day 2012, used ATT upgrade 2. Unlocked it via some website for 2$, TMobile Sim worked 3. Got it replaced Jan 2014 for broken ear piece. 4. Next one did not recognize sim, called Applecare bc Apple store is far frm my current location 5. My replacement iPhone 5 were all unlocked. 6. Applecare sent me advanced replacement, wouldn't activate 7. Sent another one, flash didn't work. Went to apple store and that phone had scratches and scuffs so went home. 8. Applecare upgraded me to a free iPhone 5S, but a ATT one. It is my understanding that since this phone being shipped to me was not purchased under contract, it should already come unlocked correct? So do I just plug phone in, restore it and thats it to check? Wasn't as short as I thought, sorry lol.
