Source : Hackint0shMembers from Hackint0sh Forum have successfully developed a solution to modify the iPhone EEPROM in order to software-based unlock the SIM.
Of course, many websites, including some renowned ones, have tried to compile information from different sources, but the original information will be found only at one place: http://hackint0sh.org/forum/showthread.php?t=1315.
It remains unclear if members from Hackint0sh have been analyzing the procedure used by iPhoneSimFree to build their own solution, or if they independently obtained the same result. The name of this free iPhone SIM unlocking solution is already known: iUnlock.
