ToySoft let me know that they have released a new application that allows you to save all your incoming, outgoing, & missed calls to your calendar on your Berry. It even supports conference calls and identifies each call and incoming or outgoing. My favorite part is that it stores the duration of the call also.
This makes it a great way to bill and track your time on the phone. From the calendar you can then easily add a note/reminder to the entry giving it some more functionality. I think this is a great way to free your call log from your BlackBerry since RIM does not offer a simple way to export it.
