iPhone Carrier Unlock

If you have an iPhone or are planning to purchase one then you might already be aware of the fact that Apple has contracts with certain cellular carriers (Mobile Phone Operators/Service Providers) and offers its iPhone along with a contract of the user with the cellular company. By default iPhone is locked to work only with the certain approved cellular carriers such as in the United States of America the Smartphone only works with AT&T and Verizon while in the United Kingdom iPhone only works with O2.

Although iPhone is available factory unlocked from the Apple apps store but it is expensive so users prefer purchasing iPhone along with a contract to a cellular carrier. The problem arises where the user wants to use another cellular company services on his iPhone like in the US a lot of iPhone users want to activate T Mobile Services on their iPhone but the iPhone is bound to work only with AT&T.

To counter this default restriction imposed by Apple in their iPhone, hackers have found security exploits to unlock the iPhone Baseband and remove all the restrictions that confine iPhone only to the selected cell phone carrier.

The procedure in which the iPhone is hacked to allow all cellular carriers work upon it is called “iPhone Carrier Unlock”.

In order to carrier unlock an iPhone, the user needs to jailbreak his iPhone first. You can read the introductory tutorial about Jailbreak iPhone.
