    So we baby our users (a lot) and it seems the "Exit" softkey in VisualVoicemail creates some undesired functionality (it defaults back to VV the next time "messages" is pressed) and we'd prefer that the users are "forced" into using the messages button to exit VV.
    Can I download the JAR file for VV, rebuild it and put it back up to the Unity servers?  I have done everything necessary (I believe) except for reuploading to Unity.  Everywhere I read, they say that VV is "included" with newer releases of Unity, you don't upgrade VV separately.
    Any help is greatly appreciated, thanks!!
