Hello my friends, I have 2 iphones 1 black 32gb and 1 black 3g 16gb. Since i have bought the 3G@16gb i have always had the problem that if i set "REQUIRE PASSCODE" I had only this options: Immediatly After 1 min After 5 min After 15 min After 1 hour AND NOT : After 4 hours (in the black32gb i have also this final option). It was not a big problem because 1hour was fine for me , but yesterday i have bought a white32gb to replace the old 3G@16gb . I have upgraded his firmware and restored the backups of the 3G@16gb on the new white. And.... BAZINGA now i have only this few options: Immediatly After 1 min After 5 min After 15 min .... is my iphone kidding me ? what can i do ? in the older black32gb i still have has maximun option the 4 hours setting , but in the white now has maximum is only 15 minutes ... do you have some advice for me ? because I really have no idea on where is the problem .... every time i buy a new iphone i have a time option erased.
