I saw a breathless, panicked post on some forum the other day where a guy thought he'd found a huge security flaw in iOS5- it seems if you double-click the home button and load the camera, and then press the home button, it goes straight to the home screen, bypassing the lock screen!

People variously could and could not replicate it, until someone finally mentioned that the lock screen only shows if it's been locked for more than a (user-configurable) length of time.

So when people who never use the lock screen went to turn on the lock screen and immediately test it out, shockingly they didn't have to enter a PIN!
