Following the release of SAM unlock solution for iPhone 4S, iPhone 4, and iPhone 3GS Dev-Team has updated their RedSn0w tool so that users can back up their activation records from /var/root/Library/Lockdown. RedSn0w 0.9.10b8 features the ability to backup arbitrary directories into a zip file and save on your PC or Mac. To save the unlock activation records for their jailbroken iPhone, users can simply run RedSn0w on their computer and click on Extras>Even More>Backup . Creating this backup will be useful for anyone using SAM unlock on his or her iPhone.
Update #3: 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 (more on that in a later post!).
Update #3b: The 0.9.10b8b update to redsn0w makes the zip files more compatible with the native Windows explorer (which doesn’t like leading slashes in the filenames).
