A tip for the iPad is always put your things in Evernote. My iPad was updated and the update crashed. I lost a lot of things like my pictures, some of my notes, Skitch and Voicecards. I have started putting all of my notes and some pictures in Evernote so I will not lose them. A good tip is to use Evernote in case you are in this situation.
I also lost all of my photos from the update! That is a really good tip! I will make sure to put everything in Evernote!
Thanks this is really helpful!
