Well they need to release another update for the iPad 4th gen too because I'm getting glitches and a terrible lag while typing.
The keypad freezes and it takes me forever to enter any text!!!
yours says up to date because you probably running iOS 7 Beta, Any way you don't want to upgrade from your device to much junk stays over from your older firmware. Only upgrade from the new iTunes that just came out! it's a clean restore ( Do a backup & restore ), and if you want to jailbreak ( if it will ever come out ), only a clean restore will work or recommended by all the jailbreak teams.
