Hey, I have not been able to use my N900 at all due to the N900 SIM issue before last week. so when I finally got it to work....and the deeply integrated Skype function and my Nokia BH-503 HS set-up I made my first call on N900 FINALLY !

I have to say that I was deeply disappointed, the person I talked to said it sounds like you have a pillow over your mouth...Ehhh I said.... I cannot say that I hear you crystal clear either....What a HUGE disappointment , after all these months I have a brand new SUPER device that is worse than my old N95 or ANY modern smarphone....What have Nokia been doing here.

today I made a search here and find this thread, and sad to see that BT sound quality and connectivity is a HUGE unsolved issue by Nokia.
I will return my phone to Nokia as this is unacceptable for a modern phone.
