I've been using this for months... it's a great ZERO maintenance app that records caller info (name, number, and call duration) to your outlook calendar. There is NO UI and NO start menu shortcut. It is a small app that runs in the background.
That's pretty much it... what you DON'T see is what you get
see XDA for more details
