Google has made a bunch of new changes to the Google Voice system the past few days. Your mobile number can now be used with Google Voice and your carriers voicemail can also be integrated at this time. Some of these changes are probably the reasoning for the most recent mobile version update that Ronen at BerryReview was tipped about. Of course, Google does not provide us with any changelog so we can't be certain that's the reasoning for the update. In any event, it's there and ready to be download by all Google Voice for BlackBerry users. Let us know in the comments if you find any changes.
