The iPhone Dev-Team has updated RedSn0w with the ability to save iPhone unlock tickets (SAM unlock).
redsn0w 0.9.10b8 adds the ability to backup arbitrary directories or files from your device into a zip file on your Mac or PC. The new button is Extras->Even More->Backup and it requires your device to be jailbroken with the afc2 service enabled (most jailbreaks include that). By default it will backup your activation records from /var/root/Library/Lockdown, which is useful for everyone taking advantage of today’s SAM unlock using Loktar_Sun’s trick
Here are our step-by-step tutorials that will guide you through all the process of jailbreaking iOS 5.0.1 with sn0wbreeze, redsn0w, pwnagetool and absenthe:
RedSn0w 0.9.9b8 recognizes 5.0.1 beta and you don’t have to “point at 5.0 IPSW” any more. Since the IPSW isn’t public, you’ll still need to provide it once to redsn0w (Extra -> Select IPSW).
