Well ... after having the same problem with my phone for the past several weeks, I returned it to stock and unrooted mine. It was rebooting continually after that. it wasn't an easy task to take back to stock in that condition, but I did it. It was still rebooting when the tech had it in his hand. He was stumped.

I returned to the Sprint store and had them look at it. He told me it's a known problem and was probably the system board. I exchanged my phone for a refurb for $35. I did freak out when it rebooted once I paired my BT, but has been fine ever since. It's been unrooted again (much easier this time) and a custom rom installed. It's working great.
