In this video I review the newly updated Multifl0w for iOS 4. It now is compatible with all models of the iPod touch, iPhone as well as the iPad. Multifl0w has been entirely revamped with a new Exposé style interface allowing you to multitask programs quickly and efficiently. There are a few minor bugs and glitches around but for the most part Multifl0w runs very fast on all devices.
Multifl0w is available in both the Cydia Store as well as Rock for $4.99. A free update to the latest version of Multifl0w is available if you have purchased the application previously.
