IDK if anyone has pointed this out but, it appears that this phone is on a touch pad of a MBP, an older one too since the apple logo is on the command key. With that stated the phone is much smaller than the current version, length and width. I don't think that the black back should be ruled out of the pic, look at the iMAC, the Blackbook and in the current rumor of the revision of the MPBs stating that Apple will incorporate the features of the iMac into the new look of the pro.
Only time will tell whether this is a fake or its legit, but if it was real I am sure that this person would have taken various photos. Or they just wanted to start an 11 page thread on this board. ????
