iOS INSIDE TRACK: HOW TO SAVE SHSH BLOBS AND DOWNGRADE/UPGRADE USING IFAITH!

FAITH is the world's first SHSH blob dumper. It allows you to create firmware files preinstalled with SHSH blobs, allows you to put a device into PWNED DFU mode.

The main thing is it allows you to save SHSH blobs for firmwares that Apple no longer signs.
It supports...
iPhone 3G[S]
iPhone 4
iPod Touch 3G
iPod Touch 4
iPad 1G
Apple TV 2
It dumps the physical SHSH blobs to the device and guarantees your ability to upgrade and downgrade to any firmware that there are SHSH blobs for.
The program also allows you to save the physical SHSH files to your computer for safe keeping. These SHSH blobs are also saved to a server in the clouds...
And you can download the SHSH blobs to your computer from the server, so you always have the SHSH blobs for your device wherever you go!
It is also a lot faster than sn0wbreeze and has lots of performance enhancements and upgrades.

Another important point is this program eliminates the need for the TinyUmbrella TSS Server. It presigns jailbroken firmware files and blocks Apple server pings for firmwares that have been edited by iFaith.
