iPhone Dev team have finally done it. The new version of redsnow is out and with it brings many functions and one of the most important features is the ability to downgrade to a lower firmware for iPhone 4S, iPad 2/3 and get your jailbreak back!

You can now finally downgrade your A5 devices to a lower firmware with this redsnow 0.9.11b1. Here are some details of the new version of redsnow.

Features of Redsnow 0.9.11b1:

• The new feature is at Extras->Even More->Restore

• You cannot downgrade without the personalized SHSH blobs for your device at that lower firmware.  You need to have fetched those blobs while the signing window was open, using either Cydia’s built-in TSS@Home feature, or with TinyUmbrella.  The new Restore screen of redsn0w lets you choose either the remote blobs or local ones (for the earlier firmware).  If you don’t know where TinyUmbrella put your blobs, TinyUmbrella has a button that will show you (copy them out of that folder and feed them to redsn0w).

• The A5 downgrade method actually updates to the latest firmware before downgrading to the earlier one.This process updates your baseband to whatever is newest.  DO NOT USE THIS METHOD IF YOU RELY ON UNOFFICIAL UNLOCKS of your iPhone4S.  Those who used the temporary SAM technique to unlock their iPhones to specific SIMs shouldn’t be affected by this baseband update.
