The image above really tells the whole story here. We’ve known for a long time that T-Mobile is planning on rolling out Visual Voicemail on their network. T-Mobile virtual tour page for the myTouch 3G gives us an indication that they are planning on having an app on the Android Market called AppPackTM that will give myTouch 3G users (and we’re hoping G1 users) access to Visual Voicemail on their handsets.
If you’re wondering why T-mobile would release Visual Voicemail as an app rather than including it in the phone itself, the answer is quite simple. If the myTouch 3G shipped with this application pre-installed, any updates to it would requite an OTA firmware update. Having AppPackTM on the market will make it a lot easier for T-Mobile to improve the service and push out updates to those who want to use the feature.
