Actually when i first bought mine (last time) i immediately freaked out when i read about the USB problem so i ripped it open and glued the usb jack. Heck i am not even sure if mine had a problem all i know is i ripped it open and applied. Then i started to have the screen crackling pressure problem .. its the one where when you tap on the screen (at the top) it would make a funny crackle sound. Its documented on the forums here. I am curious if nokia managed to push out a new batch of the n900s with these issues resolved... that's really my main reason for this post.
also, maemo still doesn't have the simple ability to assign a caller their own ring-tone! way to go!!!
