Gizmodo has posted teardown pictures and analysis of the iPhone 4G prototype they obtained.
There are a number of interesting facts gained from the dissection, the most important of which is more concrete confirmation (as if we needed any more) that this phone is from Apple. There are three separate places, inside the case, where APPLE is written prominently. Upon unscrewing the bottom two screwsjust like with the 3GSyou can use a suction cup and pry off the back portion of the phone, not the front like on iFixit's 3GS teardown.

Imagine what apple/nokia/motorola would have paid for the prototype? Waaay more than $5,000! That guy who sold it to gizmodo is an idiot! I guarantee that phone is worth a good $50,000 to apple or even more to a competitor.
The dude lost the phone. Giz bought it. Getting the exclusive scoop on stuff like the next iPhone is their job. Sucks for the dude that lost the phone, but I guarantee you he wasn't supposed to be out drinking with a secret prototype in his pocket.
If you screw up at your job in a way that messes with your company's highly successful business plan and makes them look foolish, you can't count on other people to cover your tracks for you.
