I just upgraded my ios to 5.1.1 and now i cant use my map, it always show 'can't determined location' and there is no picture on there, i cant use youtube too, it always show 'cannot connect to youtube' what should i do?
Thanx.
Have you tried turning off your iPad completely and then power it back up (rebooting)?
Many times this can solve the problems you are describing especially after upgrading the iOS.
I realize the upgrade rebooted your iPad but try it again, it can't hurt aand may solve your problem.
