Is this the next iPhone?

According to Engadget, the site that scooped the pics, this prototype was “found on the floor of a San Jose bar inside of an iPhone 3G case” and supposedly features a front-facing camera and 80GB of internal memory. Here’s what we’re betting on… we do think this unit is actually real and not a fake, clone or anything else. But, we’re guessing it’s very — and we mean very — early along in the prototype phase. Not to say the final design isn’t all ready to go, but we’re guessing this isn’t it. For starters, look at the seems in the aluminum casing. You think Apple, of unibody fame, would not have a single piece of machined aluminum for the bezel? Also, the phone appears to be flat, like, completely flat on both sides. That basically goes against almost all of Apple’s principles. Additionally, look at the back of the phone. It actually looks it’s supposed to be the front of the device. You can clearly see either a piece of glass or plastic that’s fitted into the case much like how the display is on an iPhone 3GS, or the display on the iPad. Look at the material around the sides of the back of the phone, you’ll see what we mean. So, we do think this is Apple-manufactured, we just don’t think this is anything close to what we’ll see announced in June. What do you guys think?
