I wish I had because it felt like I was picking on you. The reason that I don't think you're correct on this is because they don't require you to declare whether or not you're going to use MS Exchange at purchase. The MS Exchange configuration will be done on the phone by the user and on the MS Exchange server by your IT department.

There's no mention there about any increased rates. Business customers will get the increased data rate automatically when they purchase their phones.
