My TP (Sprint, stock ROM) was working this morning when I noticed the time change hadn't updated, so I powered it off and back on....now, it gets to about the "Launching Touch Flow 3D" message, then it cycles back to the POST screen and starts over.

Any ideas? It's moderately responsive during the boot process, but I haven't been able to actually get into anything before it resets. My only guess is that something in a startup program is corrupted, but I don't know how to suppress them. The only things I have loading at startup are Gyrator and a GPS program (GPSToday, I think it's called?).
