...about the final product, that is.
There's an awful lot of speculation going on here over whether this was a controlled leak or a planned "accident" on Apple's part, but I think all of that (while entertaining) completely misses the point. Haven't any of you ever been to an auto show? Does the existence of thousands of exotic concept cars prove that they are -in fact- what the public will find in the showroom months later?? Crikey, if that were the case, 90% of the cars on the road would have gullwing doors by now.
Authentic or not, the existence of a test product in the wild proves nothing about the final form the next iPhone will take. They still have to have purchasing agreements with and reliable order fulfillment from sub-component manufacturers. So far, I haven't seen any of those (often much more reliable) leaks.
