*** THIS METHOD IS FOR THOSE WHO ONLY HAVE THEIR 5.0.1 SHSH BLOBS SAVED IN CYDIA AND DID NOT SAVE THEM IN iFAITH OR IN TINYUMBRELLA. THIS METHOD REQUIRES YOU DO A TETHERED JAILBREAK ON YOUR CURRENT 5.1 iOS AND THEN INSTALL iSHSHit APP FROM CYDIA TO GET YOUR 5.0.1 SHSH BLOBS****
For more info on SHSH Blobs read here..http://www.ipwnrepair.com/?p=1054
So long as you've saved the SHSH blobs of the firmware you wish to downgrade to (Cydia's homepage will notify you ), then you can quickly remove yourself from what is fast becoming a fiasco of an iOS 5 release.
Important Note: Before you begin, keep in mind that the iPhone 4S cannot be downgraded to an earlier version of iOS, unless Apple is signing that particular firmware version to which you're downgrading to. Only the iPhone 4, 3GS, iPad 1 and the iPod touch users can downgrade back to both iOS 5.0.1 (custom firmware only) and iOS 4.x as long as they have SHSH blobs and APTicket saved for the firmware they are downgrading to. iPad 2 users can only downgrade back to iOS 4.x as long as they have saved SHSH blobs for it.
