iPhone-Dev Team has released Redsn0w 0.9.12b2 with a new rocky-racoon injection option and an iBooks bug fix.Earlier, this week Redsn0w 0.9.12b1 was released which enables users to install rocky-racoon in two different methods for A4 devices-backup/restore method and limera1n-based ramdisk install.
Redsn0w 0.9.12b2 has support for A5 devices which also includes iPhone 4S, New iPad,iPad 2 and A4+ older devices.
“Update #1: Starting with version 0.9.12b2, redsn0w will now explicitly ask users with limera1n-able devices whether they want to inject rocky-racoon using the DFU ramdisk method, ro the backup/restore method (the ramdisk method is better for those with lots of media on their device that would create very large backups, and it’s required for those with unactivated iPhones). If you’ll always want to use limera1n, you can select that in the Preferences pane. It also fixes an iBooks issue an old-bootrom 3GS iPhones, and provides more useful error messages when things go wrong.”
The backup or restore method is supported by iPhone 4S, New iPad,iPad 2,iPhone 4, iPhone 3GS, iPod Touch 4G, iPod Touch 3G and iPad 1.
DFU RAM Disk Method is not supported by A5 devices which includes iPhone 4S, New iPad and iPad 2.
Backup or restore Method is similar to Absinthe Jailbreak.
Ramdisk method is preferred if you have lots of videos, music and pictures in your device.
The new version of Redsn0w resolves issues such as iBooks of old-bootrom 3GS.If you have already jailbroken your device there is no need to install the latest version.
