I keep having a problem with my iPad. Every now and then I will go to my contacts and either when I open the contacts, or while I'm searching through them, the screen will all of the sudden go blck and the contact app will close, and when I reopen the contacts app, all of my contacts will be gone. The first time this happened my backup failed as well. I now have a back up on me.com, but. Y contacts will still mysteriously erase and I would like to know a solution, if there is one, to make them not erase any more.
