How To: iOS 6 to iOS 5.1.1

[toxic]

for those who don't like the new Maps or whatever else, this worked for me on an iPhone 4S:

Downgrading is identical on an iPhone, iPad, or iPod touch.

Turn the device off, connect it to the computer via USB, and launch iTunes
Place the iOS device into DFU mode: with the device off, hold down the Power and Home buttons together for 10 seconds then release the power button, continue holding Home button until iTunes notifies you of a device in recovery mode being detected. The devices screen should stay black as if turned off.
Restore within iTunes through either method a or b:
a: Restore from the iOS 5.1.1 backup you made prior to installing iOS 6 beta
b: Restore to iOS 5.1.1 IPSW by Option-Clicking the “Restore” button, and then restore from iCloud backup when finished
Let iTunes restore back to iOS 5.1.1, the device will reboot when finished
Typically you can’t downgrade iOS versions so easily, but because Apple is still signing iOS 5.1.1 this allows downgrading to commence with minimal effort.

Note: this may or may not work in the future, since Apple has to sign off on all restores (from what I understand)

Thanks, I might give this a try tomorrow for my iP4.
