Google Voice for BlackBerry have been updated to version 0.2.0.2, you can now check your balance, and will see banner notifications, the new version also offers faster dialing due to the implementation of a new feature for how the Google Voice app makes phone calls and speeds things up, according to Google this is what this new feature does:
Until today, the Google Voice app had to make a request to the Google Voice server every time you wanted to make a call to send us the phone number you wanted to dial. Then the call would be connected via a Google Voice access number. With direct access numbers, we assign a unique phone number to every person you call. This means that we no longer need to use your data network to access the server each time you make a call, so calls will be placed much faster.
