I had a jailbroken iphone 3g. Before I upgraded to 3.0 I backed it up and put it in DFU mode. When I went to sync it to restore my back up and get my music back none of the music I bought on my iphone synced with the phone and I also no longer have those songs in itunes. I have no idea why! Is there anything that can be done? I didn't have a lot of music, but I hate to have to buy it all over again. TIA!
