I've done a series of usability fixes on Orbiter for the Voicemail UI.
While it is not perfect, it is far more usable now than it ever was.
* Actual Voicemail info! Caller ID, Timestamp, Duration!
* Addition of jog shuttle for scooting forward/backward through a voicemail.
* Implemented missing voicemail functionality for _ALL_ orbiter targets, including cell phone, and Cisco 7970.
