I was looking at 9to5mac today and they posted this

It is a pre-release model using a very basic OS on it but it has some powerful options such as turning on/off freq bands and probably more.

Could this be a earlier version of the "burn-in" os that was found on some shipped iphones and ipod touches?

Interesting read but I find it hard to except on face value

The things you see could be easily faked
