AT&T Connect Participant Application for iPhone and Blackbarry

I am planning to buy a mobile which can support AT&T Connect Participant Application .
On #-Link-Snipped-#they have applicaiton for iPhone and BlackBerry . But are these applications support fully on mobile devices like whiteboard with audio and video?
I have to attend online classes on AT&T Connect application from my PC.
As per I know there is no such application for android. (Otherwise I always prefer Android)
Is there anyone tried AT&T Connect on iPhone or Blackberry, please help me out, does it support whiteboard with audio and video?
