Just got off the phone with Nokia after my lastpost... They said my device was a Non-U.S. device. Thankfully, the store I bought it from is giving me my money back!

Seems to be a problem with IT2007 even on the 770 (Hacker's Edition). I added a feed last night and shortly thereafter the reboots started. It would get past the stupid hands image and then go to a white screen for a while, followed by a brief black screen and back to rebooting.

I tried turning off our wireless connection, but that didn't help. Nor did turning off the lifeguard (although seeing the device via USB and being able to run the flasher on it certainly cheered me up). Finally I had to reflash the whole system and start over, which means I lost all my apps and settings but the device is now working again as normal.

One thing I did not try was popping out the battery to reset it, since someone on the forums seemed to indicate that they though this caused their WSOD (and I don't want that!).
