iPhone App for Displaying Email on a Locked Screen with Exchange Support I have an app, "mail notifier" that sends notifications to my phone when I get a new email, it does not support Exchange though.

Is there an app that is similar that does support exchange, maybe an app that does 'local' notifications so there is not a reoccurring cost?
iOS 5 has added this feature to operating system, and no app is needed to accomplish this task.
