If you have a Google Voice account (formerly Grand Central) you might want to check out their new application for Blackberries and Android phones. It appears to do a lot of what the GVDialer does, but it is free. You can send SMS messages and place calls using your Google Voice number. If you have a plan where you can add a number to your “circle” or “friends” you can add your Google Voice number and drastically reduce the number of minutes you have to use. Google Voice is still in a closed beta, so there doesn’t appear to be a way to sign up for an account if you don’t already have one.
What a pity !Why no Windows Mobiles version?
