One of my friends sold me an iphone 5 and i paid to have it unlocked through negri electronics unlocking service. What i want to know is, my friend is cancelling his contract due to leaving the country because of a family emergency. The att rep that cancelled his contract said the phone can not be unlocked for 2 years. Does that just mean it cant be unlocked for two years by att or is the imei going to be blacklisted?
