I’ve posted briefly about the Friends app for iPhone before and today I finally got to do a test run of the app to see what the fuss is all about. All in all, it’s worth it at $1.99. The app brings together all of your contact lists from Facebook, Twitter, LinkedIn, Myspace, and Instapaper without actually merging them (this is a good thing) and allows you to seamlessly switch between the apps within each contact. It’s a pretty vital tool for getting all of the info on one person in one place rather than having to switch between different apps.

It’s got some kinks to smooth out, but I have no doubt that I’ll be using this app for as long as I have an iPhone. Get it here.
