Apple testing Multitouch gestures on iPhone too?

BGR has received a couple of screenshots that are indicating that Apple is testing the multitouch gestures seen on iPad on the iPhone as well. The screenshots are taken from an internal test iPhone model. Apple has already informed the developers that these multitouch gestures will not be released to public in iOS 4.3.

So are these  going to be released in iOS 5? and will we ever see iOS devices loosing their home button, because that is the only way these gestures that require four or five finger will get enough on screen space to be performed conveniently.

And one thing that should be kept in mind is that these multitouch gestures are in testing stages only, and Apple will not release them until they get the right recipe.
