im new to the n800 so its possible theres other things going on that might interfere, if noone else has had these problems then its probably my unit that is bugged,

to answer some questions

i was downloading 700MB avi's i had ripped on my main machine to stress he connection abit (its great when it gets going a steady 600KB/s) somtimes when it crashed it rebooted the nokia (might have been using version 18), on version 19 it just seemed to lock up when the screen went off, and on the preferences menu.

dunno what version of os2008 im using i will have to check, il assume its the newest, but i updated on the day i got it so i cant be sure.

thx for your help, im sure i will locate the problem if its with the unit.
