An AT&T executive at the Symbian partner event made a statement (Yahoo! News article) that Symbian is "a very credible and likely candidate" to become the single smartphone OS of choice in the future for the wirless carrier. However, there are caveats to that statement that make the news really a non-event IMHO. AT&T stated this consolidation into a single OS is focused on AT&T branded devices. The iPhone is specifically excluded in the interview and RIM may be as well because there is no AT&T branding on the BlackBerry devices. That just leaves Windows Mobile that still has AT&T branded devices, such as the AT&T Tilt. So in reality, hasn't AT&T already consolidated their branded products on a single smartphone OS?
