For anyone getting "server problem" when attempting a voice search with 2.1, it appears to be a issue with random existing gmail accounts. This feature never worked for me with the 2.1 beta. When I flashed the release, I tried every one of my 6 existing gmail accounts with no love, then I created a new account on the phone and wahlaa voice search works. Now all I have to do is export my contacts and calender to the new account and contact beyondpods author to get a new key.
