Clever Weather App Displays Temperature on iPhone Home Screen  ⚐

Weather app uses notifications to display info on home screen: "We are all familar with the red iOS badge that displays the number of missed calls or unread emails on your home screen. The Fahrenheit – Weather and Temperature on your Home Screen app takes advantage of this notification system to display the temperature on your home screen. It's a clever use of Apple's built-in system that does not run afoul of the App Store guidelines."

Ha, this is very, very clever. It's a workaround that shouldn't have to exist (and, I'm guessing, won't have to exist after iOS 5 is released). But it's still super clever.
