No camera icon on lock screen even with double click
I have upgraded to ios5 and although there were a few glitches (deleted all my apps) it all seems to work, EXCEPT there is no camera icon on the lock screen. Yes I've tried double tapping the home button. It only opens up the Music controls. I tried resetting the iPad but that didn't work. I could try to re-install ios5 but I don't know how to do that...back to iTunes and do a restore? Will I lose all my apps again?
iPad 2, iOS 4.3.1
