3.1 upgrade -- Aside from daily 'coma' mode, iPod function crashes

Aside from daily resets due to the 'coma mode' issue that a lot of us are seeing, I've noticed recently that when I use my iPhone as an iPod it will crash when switching between songs if I skip forward, or if the song ends and the iPod is trying to move to the next song. Has anybody else experienced this issue post 3.1? I'm not sure if it's a 3.1 issue or if I'm having other problems with this phone. It's a release day 16GB 3G.
