Found it on windows blogs
There is another called outsync but its not as good.
A program to use Facebook friends profile photo as your phone's contact pictures!
Should mention the fact that this actually syncs the photos with Outlook, which you then sync with your phone as normal. If you don't use Outlook (like me) this isn't much use.
Still, a good app if you do though
