I'll have to give this another try again soon. I am pretty busy at the moment, but it relates to something known as Push Notifications for Apple's iPhone and iPod Touch devices using OS 3.0 and up.
Push Notifications are a way for users to get updates from their iPhone Apps even when the App itself is not running. When an App is not running, a little "badge" or notification symbol appears on the App's icon.
A notification can originate from my website and internal database, and it can be sent outward through a PHP script. However, I am getting connection time-out errors which could be caused by any number of reasons. As I've stated earlier, I'll give it another try when I am less busy
