Finally, after a long wait that lasted more than 6 months, the opening of a network for all devices running the iOS 5 system was released through a modification to a Cydia application called SAM. Until yesterday, network unlocking was available through external chips that can be installed with the SIM card, such as GeForce Sim and others, but this solution is expensive, as its price is tens of dollars, but finally, network unlocking has become available for free through the SAM application.
