Factory AT&T iPhone Unlock

An hour ago I wrote a guide on how to downgrade iOS 5.1 to iOS 5.0.1 and 5.0 on iPad, iPhone 4, 3GS and iPod Touch using iFaith. (The full guide you can find here). But this method is not working on iPad 2, because you can downgrade iOS 5.1 on iPad 2 to iOS 4.3.5 and below. So I decided to write you a guide on how to downgrade iOS 5.1 to iOS 4.3.5 and below.

Before we start you need to save your SHSH blobs in Cydia using TinyUmbrella. In case you don’t know how to do that then use this link and perform this.

Note: This process is not working on iPhone 4S.
