Starting with iOS 5, Apple issues an AP Ticket everytime you want to restore. This is in combination with the regular SHSH blobs checking procedure. So, now if you want to restore to an older iOS 5 version, you need the AP Ticket as well as SHSH blobs.
This was not possible until the iOS hacker, iH8Sn0w, released iFaith v1.4. With iFaith 1.4, you can grab the AP Ticket as well as SHSH blobs that’ll help you to restore to an older version of iOS 5. The current version of iFaith is only available for Windows and is compatible with A4 devices only and not the newer A5 devices. This means iFaith 1.4 is compatible with:
- Apple TV 2
- iPad 1
- iPhone 3GS, iPhone 4
- iPod Touch 2G, 3, 4
How To Use iFaith 1.4 to Dump iOS 5.0/5.0.1 SHSH Blobs & AP Ticket?
