According to AppleInsider sources, iPhone firmware 4.0 will bring multitasking to the platform in coming months. And it may look at lot like Exposé.
The "full-on solution" to multitasking will support "several" third-party apps running at once in a "multi-tasking manager that leverages interface technology already bundled with its Mac OS X operating system". To us, that sounds a lot like Exposé, a multi-window view that's already found its way into phones like the HTC Legend, which would be quite different from the proof-of-concepts we've seen thus far (like our lead shot).
But frankly, I don't really care what it looks like, so long as I can pull up my email while web browsing as easily as I can on any Android phone. The iPhone's uni-tasking Gmail support is straight-up punishing in comparison. [AppleInsider]
