I agree with this theory over the media card bbthumbs.dat (although I am sure that corrupt bbthumbs.dat's do clear it up for some).
From reading elsewhere, 3G seems to work okay, but the handoff from 3G to 2G does not and causes a reboot. To test this, I switched to 3G only, and so far no reboots. I am going to test it further and go 2G only after I have given it sufficient time to confirm this. If that works, I will try 2G & 3G again, and if the reboots resume, I will keep it on either one until the next 5.0 (leaked or released).
Update: 2G only rebooted, so staying on 3G only (which if I understand, AT&T users cannot set their BB's to, as the option is not there).
