I also found that if you have iOS5 on an iPhone 4, the new camera button allows you to access apps and what-not without unlocking the phone - though it thinks its locked.

Double click the home button to get the camera icon, go to camera and press home button and you can access all apps.

But if you try to go to the photo gallery, the phone tells you its locked and wont go there.

Incorrect. That only works if the device doesn't require a passcode to get past the homescreen.

Yes, I thought that might be the case - and I createda passcode after I typed this and this is true -- however it still does not allow you to access photos through the process I described. It shows you a locked screen.

Right, it only lets you see photos you've taken from the lock screen, so no personal data is exposed.
