I'm not seeing this on my production machine - which is currently  
linked to 1 iPhone 4S, 1 iPad, 2 iPod Touches, and 3 android devices  
of varying versions.

That being said, ActiveSync, itself does not need the session and was  
originally coded to disable sessions. However, some of the code paths  
in the applications rely on authentication information stored in the  
session. See http://bugs.horde.org/ticket/9733
