I've got the reboot bug too I've ordered my N900 from nokia.nl and I'm running FW 1.2009.42-11 on the Dutch carrier T-mobile. it's rebooting since I took it out of the box I've reinstalled the FW with NSU twice, no fix... this morning my N900 became a brick and got stuck during start up. Luckily i got that fixed with flasher 3.5. however, the rebooting still occurs it's kinda hard to enjoy my new toy when it's constantly rebooting
