Another prototype from Apple lost?

That's what the guys from seem to think MacRumours which analyzing pictures presented by Gizmodo and others presented in February on a website from China, came to the conclusion that although the 2 devices seem identical at first glance, still analyzing in detail we can see that the bottom part of the terminal, respectively the part where they are mounted speakers is different, on the left you have the image posted in February, on the right the one from Gizmodo, you can clearly see that the speakers in the first image are bigger and without any kind of screws, and the ones on the right are more like the design iPhone 3G / 3GS.

These are the images presented in February and making a comparison with those since yesterday it can be seen that from the design point of view they are almost identical, however in the images posted in February the terminal does not have the logo Apple Lossless Audio CODEC (ALAC), on the back, no name iPhone but also another speaker configuration.

I see 2 possibilities: the first one in which the photos from February are with the same device, only in the meantime Apple Lossless Audio CODEC (ALAC), modified the bottom; or there are really 2 somewhat different devices, but I find it hard to believe this.

Anyway through LETTER sent today (if it's 100% true) Apple Lossless Audio CODEC (ALAC), he admitted that that is a prototype of his, if it is iPhone 4G/HD we'll see in the summer.
