AUTDv1 Text Messaging Impact

With Exchange 2003 and Windows Mobile 2003, Microsoft attempted to mitigate the wide-spread usage of RIM BlackBerry's push email service with a technology named Always Up-To-Date, or AUTD. This first version of AUTD worked by sending an SMS control message to the Windows Mobile 2003 phone whenever an event occurred within Exchange which modified a folder marked for synchronization. The Windows Mobile 2003 phone would then download the updates from Exchange.

Image1 shows a chart detailing my text message usage from August 2005 through July 2007. It is fairly obvious the period where my usage of AUTDv1 starts and ends.
