UPDATE: (3-19-2011)
As we prepare to migrate to Exchange 2010, we have implemented a coexistence solution that may require you to use legacy.unt.edu as your incoming server name.
In our testing (iOS 4.3 was used), when you configure your iPhone Exchange ActiveSync profile, the AutoDiscover service will enter this information in for you automatically.
