| Its very important for all people who trying to restore and unlock their iphones after they have it unlocked
to make sure the AT&T iphone is activated by any ATT Sim,
you must see 1st activation date: when you check your imei
if you see first activation date in imei check, then your good to go, restore thru i tunes
if you don't see 1st activation date on imei checker, means your iphones hasn't been activated , you must use restore your iPhone insert att sim card
then restore again and insert any other sim as u wish
good luck ! |
