Today I have for you 3 FCC listings for 3 devices from 3 companies from 3 different parts of the USA. The listings have nothing in common aside from the fact that they have everything hidden, they're using similar model numbers, and they have pretty much the same FCC label design as on the current Kindles.
Two of the devices have Wifi and the other has 3G. I disagree with my source about which is which, but we agree that these belong to Amazon. The similar model numbers and virtually identical labels are too much of a coincidence.
The image above is from one of the listings. That is the backside of a Wifi equipped D01400. I'd estimate, based on the diagonal, that it has a 7" screen. I expect that to be the device that Amazon will show off tomorrow. BTW, the D01400 is from a dummy company by the name of Okakopa. The name is a Hawaiian word that means October. Some one at Amazon clearly has my sense of humor.
I don't have time today to trace the dummy companies back to Amazon; that would have to wait for business hours, anyway. But I will be taking a deeper look into this later in the week.
