Is this the T-Mobile-branded Sidekick III?

Is this the fabled Danger Sidekick III? We can't say for sure, but the site that reader John M. tipped us to contains this solitary photo, which looks almost identical to the shots that have been leaking out for the last few months. Although no explanation of the picture is given, John claims that its from T-Mobile's advertising campaign for the device, which sounds pretty reasonable to us.

[Thanks, John M.]
