If in fact they will be giving away a free unit to all attendees, I would have to assume that this gathering would have to be somewhat "invite only" - meaning all attendees should have some sort of relationship wtih Cingular &/or are part of the press.
If they do let anyone in simply by registering, this leads me to believe that no devices would be given away.
