Evasi0n jailbreak solution now supports iOS 6 and iOS 7 devices. iOS 6.1.3, 6.1.4 and 6.1.5 iPhones can also be jailbroken thanks to P0sixspwn method. In other words, all Apple handsets with iOS 6.x can be both jailbroken and unlocked. You can perform iOS 6.x iPhone unlock using SAM activation tickets.
Here is how you can unlock your device and connect to any SIM card. You just have to save SAM tickets for this procedure. It is necessary to note that your baseband must be preserved with Sn0wbreeze program.
Users who didn’t save SAM activation tickets are out of luck for this unlock. They have to use other methods, for example, GEVEY SIM unlock or factory IMEI unlock.
