People who work with me know that I love the feature in Outlook where you put your picture in your contacts, their photo shows up at the top of their emails. It also shows up on a synchronized smart phone that draws contact cards from Exchange.
The LinkedIn application for the Blackberry takes it a step further. If someone does not have a picture, and you have linked in on the BB, it will update the picture in Outlook. I know this as a bunch of pictures started to show up in contacts with the little linked in icon in the bottom corner.
Well done Blackberry. You can get the app here.
