Exchange sync uses different protocols - been a while, can't recall which (RPC over HTTPS maybe, plus some used in maintaining heartbeat with the Exchange server). AT&T can see the different traffic types and slap data overage charges on for traffic that is not within the accepted data types.

I thought that's where the whole 'enterprise plan' element of things came into the equation. Not sure how often they really analyze the traffic, really charge the overage rate - but thought this was a reason that corporates cough up - for the ease of knowing those traffic types are included ...

Seems like several people now have said that they can get "push" to work via the enterprise server using the $30 data plan. Knowing how skilled telecoms are at getting our $$, this theory about traffic types sounds believable...does anyone know this for sure?

What about battery use; does "push" use more or less battery? I have heard that the server "pings" your phone when there is a change as opposed to an continuous checking that would suck up battery. If push pings, then push would typically use less battery.
