Ok, so I didn't read it too well and now I understand,... this is a "Mock up" (Fake) using the "Rumored" new "Bezel" (Edges of iPhone). So they'ret7 not claiming this is the new iPhone. Just that the Bezel is rumored to be the new one that will be used in the next gen iPhone.
That isn't a spy shot. It is fake because it is still running the old OS. The safari in the new OS 3.0 looks completely different as you can see on http://interactiveiphone.com which is updated to firmware 3.0
