i dint really think it was this stupid but it did turn out to be..

my first day with n900..i had to tranfer a lot of contacts from my old phone..i thot i would do multiple rounds using the sim..so dint put the battery cover on..as soon as i started the phone,i got INTERNAL ERROR: APP CAMERA FAILED. device reboots 17 times n it bricks.

Am based in India and N900 isnt launched here yet..so no service n not poss to return it also..i was devastated..$600 is a lot of money here

The first thing i learned about N900 was HOW TO UNBRICK IT
thanks to this community..
