We saw the expose like multitasking UI might come to the iPhone with OS 4 and while it hasn’t come up officially here we have a multifl0w update. Developed by @aaronash you can see this thing in action below. This interface allows you to see as many as 9 apps in one screen (instead of the 4 you see in the dock) and the best part – this works with the iPad!
Exposé-like multitasking for iOS! Works with iOS4, and iPad! Totally rewritten for speed, reliability, a redesigned interface, and iOS4! Multifl0w shows all open apps (up to 9) on the same screen, for easy and quick task switching. The tabs are re-arrangeable, just drag an drop! In iOS4, Multifl0w can work alongside or totally replace Apple’s task switcher!
Available via Cydia or Rock your iPhone.
