My iPad is jailbroken and it is still running the iOS 5 software.
The following are glitches I've discovered and recorded directly (via a jailbreak recording app) from my iPad.
Self-Moving Photo Glitch on the Camera Roll (This is the coolest glitch I've found)
iPad Glitch: Infinite Zoom Out Glitch [Google Chrome App]
iPad Glitch: Invisble Square Icon in Camera Roll
iPad Glitch: Blank Photo Icon Glitch on Camera Roll
Enjoy the glitches! I'll probably update this as I find more glitches.
