If you're an iPhone user with an AT&T contract waiting to make the leap to another carrier, your jail breaking days are over.
The wireless service provider announced that on Sunday, April 8 AT&T customers with expired contracts will be able to unlock their phones and use any other service they like — except Verizon.
Seeing that AT&T and T-Mobile operate on GSM networks while Verizon and Sprint operate on CDMA networks, iPhones sold through AT&T have different hardware than those sold through Verizon or Sprint, making it impossible to switch GSM-enabled phones to Verizon.
What's more, there are a few caveats before you liberate yourself. According to a statement from AT&T, "… 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."
If you qualify, call AT&T on April 8 for an unlock code. Once you receive the code you'll have the freedom to use a SIM or micro-SIM from another carrier.
