I really need some help: Last night, I was just choosing a podcast to play on my iTouch. When i opened the music app, it said updating library. Once the music became available again, it had deleted all but one of my 700 songs. What can I do to get them back. I did not do anything to my knowledge which would have made this happen. I have another problem... I paid £4.99 for a Jamie Oliver app. I left it downloading on my iTouch for about one and a half hours. When I came back, iTunes said that it was unable to download it. When checking back on iTunes, it doesn't seem to acknowledge that I bought the app. I was charged for it on my Visa bill, too. Help!
