It's been a busy Sunday for me. Let's see -
Call To Contact allows you to easily add new incoming phone numbers to existing phone contacts with just a few clicks. When an incoming phone call is received, Call To Contact checks to see if that number is already associated with one of your contacts. If not, Call To Contact will prompt you to add the number once the phone conversation finishes.
Call To Contact V1.0 is being made available free of charge as a “thank you” to the Windows Mobile community for their continued support and interest in Windows Mobile-based solutions. Product details, screen shots, system requirements and download instructions can be found at the Call To Contact Phone Edition product page."
All in all, a busy Sunday indeed... :-)
FYI - The Smartphone version of Call To Contact is right around the corner (literally)...
