Let me just start off by saying, no this will not take the place of a real MMS app. I think that ball is in Apple's court. But Fliq will come in handy if you have a few friends with iPhones and are connected to the same WiFi network.
What is Fliq? Fliq was created by Mark/Space and is a "social networking application that allows iPhone and iPod touch users to instantly send, or "beam", photos and contacts to one another".
Now this is all fine and dandy but one thing I wish this app allowed you to do to is send data via a 3G or EDGE signal. Because lets face it, how often do you share a WiFi signal with a bunch of friends with iPhones? None the less, this app is worth trying out and for the low price of free at the App Store you really have nothing to lose. Give it a go and let us know what you think in the comments!
