HTC Blackbird?

[FlatSurfSucks]

Anyone know anything of this? Take a look at the T-Mobile HD2 specs page. (can't post link but there's a thread about it on here already). On the home screen, there's a meeting notice for "Leo/Blackbird Marketing". The Leo, of course, is the HD2. But what is the blackbird? Is it a CDMA version of the Leo? Just the name for the T-Mobile variant? Some other device altogether? I googled and turned up nada.
