Does anyone know if there is a consistant work around for this at the moment. I.e. once the Mic doesn't work, (as per previous replies), is a restart usually enough to get it going again? But then a further charge potetnially causes it to stop?

I'm still trying to work out if I could be struck by this bug, or if mine is a definite hardware or other issue instead. For example, say I fully charged my n900 - would I need to run it flat and recharge with a different charger before it had the opportunity to start working correctly?

Or am I just clutching at straws and hoping my Mic problem isn't as bad as it probably is?
