In a massive policy change, it looks like AT&T will start unlocking off contract iPhones, so that they can be used on other carriers (frequency permitting). In a press release, AT&T said that:
…Beginning Sunday, April 8, we will offer qualifying customers the ability to unlock their AT&T iPhones. The only requirements are that a customer’s account must be in good standing, their device cannot be associated with a current and active term commitment on an AT&T customer account, and they need to have fulfilled their contract term, upgraded under one of our upgrade policies or paid an early termination fee…
Apparently, mounting pressure from customers about AT&T’s ridiculous and long standing position on not-unlocking iPhones and possibly Tim Cook, has lead Ma’Bell to change her mind. Keep in mind, that you’ll have to be in good standing with AT&T and off contract, so just ended your relationship with AT&T. Hope this is true.
