The folks @ Windows Phone Hacker developed a cool application that adds Windows Phone 7–like notifications to Windows Mobile 6.5. This application displays a top bar whenever you get an email or a text message, you can click on the top bar to go to the notification, this is pretty nice! Check out the video after the break!
To use this application simply download the CAB @ http://windowsphonehacker.com/wp7_notifications_on_wm_6.5_ca85f.php and install it.
It will run in the background and display the notifications when needed.
See it in action on a HTC Touch Pro in the following video:
