OK guys/gals.

just collected my phone about 20 mins ago.

Its with trembling hands that I opened the box.
and yes, I didnt bother to charge my phone, switched it on right away ;-)

step 1: opened the phone application
step 2 : called my other phone

To my horror I realized my mic wasnt working !!!!

step 3 : switched off my phone and restarted.
step 4 : this time I made a call from my other phone to my N900.
step 5 : The mic seems to be working now.

I dont know why , but this is what happened.
Thought Id share this with you in case it works. I see no logic except that i made a call to the N900 and it started working.

Im going to do some more detailed tests abt other features. will post later.
bye for now.
