I just had a look at iOS5 and most of the stuff that they have included in this update seems to copy android A LOT but one new feature seemed very appealing. That was the ability to use the volume changer button as the camera shutter button. Comparing the iphone and galaxy s2 the volume changing button are situated at almost at the same position and same side of the phone. I was wondering if the galaxy S2 had this feature or if it would ever be implemented in the future as using the volume changer button as the shutter would be very practical.
