Wow, must have been a server roll-back, because I fixed my problem and posted a solution.
Basically I had a corrupt Email in my outbox because Sendsong crashed when I accidentally bumped into the Dock button. I had to reboot my iPhone and after that point my inbox stopped workin correctly.
What I did to fix it was uninstall SendSong and reinstall it, this time sending another song. That cleared out the cache, and the corrupt email somewhere along the way. Since then I've been back to normal, and have even used SendSong again with better results this time around. Oh, I uninstalled Dock, lol. I'll only use it now when I need screenshots.
