A new firmware called Tweak 3.1.3 has been released on Cydia. Its purpose is very simple since it will only replace the information contained in a variable pretending to be on your iPhone Firmware 3.1.3 to 3.1.2 instead.

All this will come back very useful when you try to install applications via AppStore. Now there are several that explicitly require the latest firmware, so if you do not want to update, you can simply install this tweak and bypass the problem. Make sure to jailbreak your iPhone and install Cydia. Then search “Firmware 3.1.3″ in Cydia via the BigBoss repository.
