How to Unlock Your iPhone for Free

The Apple iPhone is one of the most popular smartphones on the market, thanks to its sleek design and extensible operating system. As of 2010, the iPhone was available only to AT&T customers, leaving users of other carriers out of the picture. It is possible to unlock the iPhone for usage with other carriers, but it's first necessary to "jailbreak" the phone. Jailbreaking is the process of opening the iPhone operating system to manual configurations that are not explicitly supported or approved by Apple. Once this is done, the device can be unlocked and virtually any mobile phone SIM card can be used.
