    I am having this same problem I have talked to 10 different people at AT&T and they could not help, they said I would have to buy a new phone. I really don't want a new phone I like the one I got would just like it fixed if it can be.

The phone actually randomly just started working again. i hav no idea what i did 2 it 2 make it go off. but it randomly started again. so urs might just start working again. it took a few days before it started. but once it did, all the ringtones, grafics, and pictures returned.

I spent most of the day on Thursday on the phone with AT&T and none of the 10 people that I spoke to could help me they had never heard of this problem before and they said I would have to buy a new phone. I really like this phone and would like to fix it if I can but don't know what to do HELP!!!!

I just turn airplane mode on and off if it doesn't work, and it fixes it everytime. you could also try sending a text to yourself, that usually makes all the messages go into your inbox, like a flood.
