Gizmodo has a photo of what is being called the 4th Gen iPhone.  The photo is of the midboard of a new iPhone of which has a new design than the current offering.  Last time this site showed an iPhone part it turned out to be the 3GS shortly after.  There is reason to believe Apple would want to release a new iPhone soon due to the increase in Android phones.  Either way we know something new is slipping through the cracks at Apple.
