Ok, I just re-did the 1.1.3 soft-upgrade. Everything worked great, until I resprang again. I went to go listen to some music, and all of it was gone! However, when I looked in the seetings-general-about, it said I had no music, but still 8.1 GB out of 16. I plugged it in to my computer and in iTunes it said it was all in other. What do I have to do? Is there a fix I can do without restoring?
