Downgrades of iOS is not supported. If you search the web, you may find suggestions on how to force a downgrade, but they may or may not work. You similarly may still find direct links to download iOS 3.1.2, but beware of any links that don't point to Apple; an iOS package from any other source may contain malware.

Arent there any other solutions, except downgrade, because Logitech refers its the fault of apple's authencication of the device. and i would like to have 3.1.2 or 3.1.3 because i can still play and use some apps.
