Cydia will save SHSH/APTickets for iOS 5.0.1

Good news, Cydia is now saving SHSH blobs/APTickets for iOS 5.0.1 firmware. These blobs will be used in the future for downgrading to iOS 5.0.1. So just run Cydia and it will do all the work.

You can also use RedSn0w, iFaith and TinyUmbrella to save your SHSH blobs and create signed custom firmware.
