But ... just my recollection here, but I thought the place where AT&T does come into it is that their data rates (in the fine print) cover certain specific sorts of acceptable traffic - web browsing, consumer type email for example (POP< IMAP etc).
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 ...
If it does turn out that we have to pay $45 for MS Exchange support on the iphone, then I probably won't be using it. I'm using Synchronica now and it works fine. I just can't see paying $15/month out of my pocket just to be able to access my Exchange calendar and contacts.
