Most people who have iPhones are either playing around on one of their many apps or they are on Facebook. The Facebook Chat portion of the app is cool and all, but it is now even cooler since you can now make VoIP calls through Facebook chat thanks to Crisp App. This will allow iPod Touch and iPhone users who are connected to Facebook to make calls to your Facebook friends. This app is however unaffiliated with Zuckerberg, but it does allow it’s users to send pictures, browse message history, view a friend’s wall, use emoticons, receive instant replies with Apple Push Notifications and setup sound notifications, and it also runs in the background. Unfortunately while using this app there will be lot of lag while calling, but for $2.99 it will get the job done for Facebook Addicts.
