The new version of Google Voice which will be included with the T-Mobile G2 has been found in the system dump that’s out in the wild. Who cares right? Well it becomes news-worthy for the simple fact that this version comes packed with 2 widgets to drop on your homescreens, making your voice and texting addictions even more accessible.
Install as you would any other .apk file. It will upgrade your current Google Voice.
