fixed it! All i had to do was open itunes and click on the iphone under devices. Then On the top where it has Apps, Ringtones, music, etc. i went to music and unclicked sync music then I synced it and it worked. After that I reselected sycn music and all my music was put back on my iphone.
My work phone is a Blackberry, and it was acting weird a couple weeks ago. I had to call AT&T about something else, so I asked about the blackberry too.
The lady said it might be acting up because it is a couple of years old. I told her I have guns that are 75 years old and still work exactly the same as they did the day they were made. I think it scared her.
