Don't remember that.
If you're using Windows Vista/7 go to control panel->devices & printers
Check whether there's N900(Update Mode)

only workable if you have pc on hand, if you only got the phone and want to do some file shifting or editing some config, filebox still the best
Till now I never used filebox to move files.
I prefer terminal & WinSCP

excuse me, but does anybody know what happened to the application "Preenv"? I tried installing via apt-get, but it says package not found. I did activate those extras repositories..
also cant find it via application manager..
weird..
http://maemo.org/packages/view/preenv/It's there.
Type "apt-get update" & retry installing preenv
