In addition to learning that the Samsung BlackJack 3 is headed to AT&T Mobility later this year, the leaked AT&T 2008 roadmap has a lot to say about Windows Mobile 6.1 upgrades for existing WinMo devices. 

According to the document, most of AT&T Mobility’s current Windows Mobile offerings will see WM6.1 upgrades later this month, including the AT&T Tilt, BlackJack 2, and Motorola Q 9h.  The Pantech Duo won’t see WM6.1 until October, and the Palm Treo 750 isn’t scheduled for an update at all.
