So I started with Multifl0w because I wanted something prettier than Kirake that I had been using for a while. After crashing quite a few times, MultiFl0w works. I was only using the trial to see how it works and it works fine. But I remembered another app that I had seen previously called Proswitcher that did the same thing. Well i went and installed that, and I must say, you should be using that instead of Multifl0w. You get more options on how to activate, and the whole experience is much smoother. Acts more like cards on the Pre which is what both apps are modeld after. Bottom line, go get proswitcher, google it and add the source to rock today!
