Thankyou for the "headsup" Isamun, my N900 loses contact with the GSM-Modem all the time when i'm talking and i was about to send it back for repair, now i won't.
It will still work fine as a VOIP Phone at home and i might find some other use for it later on.
Lucky as i am, my sister was fedup with all the dissconnected calls so she bought me a xperia arc! better hw but no way near as useful as Maemo.

chers!
