Ok, so I restored to 4.0, and every time I tried to restore the backup of my phone it would never complete. It would get stuck part way and I couldn't get to the home screen.

So I gave up restoring from backup and skipped it. Now when I jailbreak I get a blank (white) cydia icon. Verbose boot, wallpaper, and multitask work... but cydia just doesn't work. When I go in it can't download any repo lists. The first time I remember checking there were only 2 repos listed. It won't recognize any repos I install manually. The last time I redid it no repos showed up.

I'm currently going back to 3.1.3 so I have a phone again!

Any help?
