iOS 5 security lock codes.
I know in iOS 4 on the ipad you can set passcodes for the lock screen and restrictions screen in settings. Does anyone know if there will be more areas in iOS 5 that will allow a separate lockcode? I hate having a lock code on the main screen, but would like to make it so someone couldn't just pickup the ipad and erase everything. A lock code on mail settings isn't helpful if someone can still do a full reset of the ipad.
I'd also like to see the option to set longer pass codes moved to the restrictions page as well as the lock screen.
