As when I saw the post on CNN.com* about finally being able to dump friends on the go. This is PERFECT for me! Sure, access to Google Maps would be cool, Angry Birds looks fun, but getting rid of faux friends on the go? That's pretty much a dream feature. Congrats, Facebook, you've finally provided the killer app that will drive me to get an iPhone.
As for you, outdated Facebook friends, get ready for unfriending!
* I mooched the graphic from there, too. Thanks, CNN!
