Looks like over Endgadget got there hands on what might be the upcoming 4G iPhone. Seems that the phone was found on the floor at a San Jose bar in a 3G case. The pictures look real, but might be a prototype. Also from what it is mentioned it talks about having a front facing camera and 80GB? That sounds off if it is flash memory because it should be 64GB. Hopefully more info gets posted, as it does look like a nice design.
Here is some of the pictures
