The next big software update for the iPhone is iOS 5, which should be unveiled this June at Apple's annual Worldwide Developers Conference. But someone claims to have a test version of it, running on a white iPhone, no less.
The big new feature on display here is a way of flipping all of your recently-opened apps across the screen, much like Expose in OS X. It also throws the Spotlight search up top, removing it from the left of the home screen, where it lives now.
It certainly looks real enough, but whether or not these are features actually coming to iOS 5 or are features left on the cutting room floor in a previous release has yet to be seen.
