Yesterday, iPhone Dev Team has released an updated version of Redsn0w. Other than supporting untethered iOS 5.1.1 jailbreak, what makes Redsn0w 0.9.12b1 different from Absinthe is that it also allows SAM unlock users to restore their unlock activation tickets.
Remember only those who have earlier unlocked their iPhone device using SAM and backup their activation tickets using Redsn0w are able to restore them. Remember SAM activation was patched by Apple and only the lucky ones who reacted quickly and saved their tickets are the ones still enjoying the unlock.
Let us go through the process of restoring SAM unlock activation tickets.
STEP 1: Download Redsn0w for Mac or Windows, extract it, open the Redsn0w application and hit “Extras”. Make sure your device is connected to your computer.
STEP 2: Click on “Even More”
STEP 3: Click on “Tickets” and browse the SAM activation ticket file that you have earlier saved. After that reboot your device and try the SIM card for which you have stored the tickets.
Remember SAM was a vulnerability found in the signing system of Apple and was able to unlock all iPhones on any baseband including 4.12.01 and 4.11.08 but it was later patched by Apple.
