about 5-6 weeks ago i updated my iphone to 3.0 (great software btw) it was all great, but i did not have access to my computer. I plugged it in to sync it today, and i pressed sync. It says syncing on the computer and the iphone, but after about 5 - 10 second, it stops. I look back and nothing has changed. Recently, my computer crashed, and i lost everything. i used senuti to get my songs back to my computer, but none of my playlists are on my computer. what do i do??
