My ipad is running iOS5.1 and i prefer not to upgrade to iOS6 until an official google map is released. However, itunes shows there is over 4gB of "others" which may make my ipad working slow. I have tried to "restore from backup" in itunes but didn't help. I did not "restore" as it would upgrade my ipad to iOS6. Would the option "reset all contents & settings" in ipad work? Will it lead to a force upgrade afterwards? Please help, thanks!
