IOS4 for Itouch, Ipad, and Iphone

Directions:
First, download iTunes 9.2.


Second, BACKUP your device in iTunes!


Third, Download the right iOS4 Firmware for your device. I recommend using firefox to download it since it downloads .ipsw files correctly and does not split it up.

Fourth, in iTunes Hold Option(Shift) and click on restore and choose the .ipsw file from your files. (Usually best to save it on your desktop)
After that, it will start restoring to iOS4 GM!

And there ya go! You should now have iOS4 working on your device.
