what makes you think its fake?
There is too much "wrong" with these leaks that makes me think its a fake.
I will admit at the very best its a crude prototype that would allow access to the parts for testing and tweaking purposes although there are too many holes in even that scenario.
1. Why has this prototype left apple? Everyone knows just how TIGHT apple are with products that aren't available, let alone even announced yet.
2. If it is a prototype, would you not want it made exactly the same way to test it properly? Clearly not a finished product and that can cause variables that seem to suggest its against Apple's stringent testing.
3. Why label the prototype? Im pretty sure everyone working with the prototype at Apple KNOWS its going to be an iPhone prototype, so why have stuff on the back saying that its an apple prototype. It seems that would be a waste of time.
4. If its the real deal then why would Apple abandon their staunch belief in the ability to not remove the battery if your an end user? Short answer, they wouldn't! Its been proven how stubborn Jobs and Apple can be. Why change now?
5. 80GB, it doesn't turn on (suddenly and inexplicably) and it has a "decidedly new OS"... seriously... Too many holes in this story that cannot be overlooked as oh thats just Apple being Apple. It goes against everything we know about Apple, what makes this iPhone release any different?
