Word of warning though. I've been using wireless deployment for a few years, and haven't had any issues until we got a few devices loaded with the 4.3 OS. I've been working with TSupport for a few weeks and still haven't been able to deploy Office Communicator to those devices (8130 for example). All other devices take the software no problem.
