this morning I tested my mic with recorder. (my 3 sim doesn't appear to work yet so haven't made any calls) i got no sound recorded and had brief panic this was some big problem.
Then I rebooted and tried again...and it recorded fine.

Done mate!

I'm from the Netherlands and having problems with the mic.
The Serial number of my N900 is 356938030126990
There are more users in the Netherlands who have the mic problems with there pre-ordered N900

We have to send it back to a company names Cycleon and we wil receive a new N900 upon arrival of the returned N900

can all posters who orderd and got the mic problem
please list on how they turned the phone on 1st time
so what happen to you "acerman" how did you start the phone and you bbrindle
also how many on here have now reported there mic no good

Open box plug in charger 10 mins turn on phone ,set it up made a call 1hr later no mic.

How many of the people with mic problems, have rebooted and tried again? I've not tried making a call yet, but recorder worked for me, but only after I rebooted.

Rebooted a few times still no go.where is the recorder on phone.

Also from The Netherlands and mic was working fine (recording and making telephone calls).

Today it happened three times that when I received a call the caller didn't hear me. After a reboot the mic was working again, so I think these mic problems can be in some way software related.

It was the first time I did a manual reboot since last monday when I received the phone. (I did pre-order.)

nuknuk: damn. after all that wait and now this. hand in there buddy

Openend the box, put the battery inside the N900 doing the setup......overnight charged the battery and turned the n900 on....tried to make a call without the mic....
