My colleague Mel Sampat has created a great application called OutSync. OutSync is a free Windows application that syncs photos of your Facebook friends with matching contacts in Microsoft Outlook. It will then sync them to your Windows Mobile device so they appear when you get text messages, emails and phone calls.
It's similar to the application that Ross Dargan wrote after my initial post stating - wouldn't it be cool if....
Mel's application uses WPF, supports transparency on Vista, and is written with VS2008 + Expression!
