I've learned, finally, to NEVER accept upgrade offers from Cydia. I recently was alerted that there were "necessary updates". Of course, because of the clumsy way Cydia is designed, you only get this notification AFTER you've already started going through the updates one at a time. However, I accepted it, since I couldn't see any problems, and it bricked my jailbroken iPad 2 for the second damn time!
The device was unusable. Sure, it would boot and start, but the screw was off (the Winterboard theme was screwed up) and anything I click on beside Angry Birds would cause it to reboot. I'd had this happen before, and it eventually fixed itself, so I waited. I even tried using the tinyumbrella 'boot fix', but it didn't help. Finally, after more than a week of dead time, it suddenly 'fixed itself'. I was about to reinstall the iOS, which would make it unjailbroken, since I can't reload iOS 4.5 and iOS 5.0 isn't jailbroken yet.
Moral of this story: NEVER update Cydia! You're better off waiting for the next jailbreak, when you'll have to update the iOS from scratch anyway. It's better to not have the 'latest' feature than it is having no device in a time of need (for me, a 3 hour flight with no music, movies or games!).
