AT&T changed its strategy regarding out-of-contract customers, allowing them to unlock their iPhones.
The carrier made the announcement in an official statement addressed to the customers who have finished their two-year agreement with AT&T.
"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," announced AT&T.
So far, the customers who wanted to leave AT&T at the end of a 24-months contract couldn't take their iPhone on the carrier of their choice. In order to do this, they had to resort to unofficial methods.
With Apple's latest iPhone, the situation would have been even more frustrating. Advertised as a "world phone," iPhone 4S could be used on both CDMA and GSM networks.
The customers who manage to unlock their iPhone 4S will be able to roam on GSM networks while abroad without their carriers overtaxing them.
