Sorry I can't offer any advise to answer your question but I do have a comment about all the precious pictures so many people have stored on their cameras, phones and computers. BACK THEM UP! Store them on a memory card, download them to a computer and have them put on a disc or thumb drive. Especially anyone that has them on a cell phone or camera. It's so easy to lose these. My daughter in law found that out the hard way. She had 100's of pictures of her new son on her phone and dropped it in the kitchen sink (full of water) one day and lost all of them. She was heartbroken! Now she emails any pictures she takes to me and I store them for her on both my computer and a rewritable disc for her. Double backup!
I sure hope you are able to get you music, apps and movies back, but if you can't, at least you can download them again. But your pictures are a different story. If you can't get them back, they are gone forever. That would be a complete shame.
