While everyone is making a wish list of iOS 5 features, please make sure to include something about an upgrade to the notifications system. Maybe while you’re at it, ask for some form of a widget feature too. Not everyone needs them, but those of us who have experienced them on other smartphones would love to see them in iOS.

The biggest benefit they bring is information at a glance. I’m currently using the WeatherIcon tweak to help me cope with the lack of the feature. At least I don’t have to pop into the weather app anymore. For folks operating on non-jailbroken devices, Fahrenheit basically accomplishes the same thing…

The app uses push notifications to bring you weather information based on your location. The current temperature is displayed in a little red notification badge, just like when you have a text message.

Unlike the WeatherIcon tweak I mentioned earlier, Fahrenheit does not replace your current weather app. My springboard generally has limited space available, so it’s tough for me to justify 2 weather icons. However, the app certainly works as advertised.

Setup for the weather software is a breeze. Just give it permission to use your location and say it’s ok to receive push notifications and you’re finished. The application takes care of the rest. It displays the current temperature from your default location, but you can add others manually by opening the app.

Launching the application also gives you a full 10-day forecast predicted down to the humidity and dew point. You can even share your current weather status with your friends via Facebook and Twitter.

If you’ve been looking for a good weather app, check out Fahrenheit. It has a gorgeous user interface and quite a few features for $0.99. An extra dollar will get you satellite maps and rain radar via an in-app purchase. Most of all, you’ll love not having to open your weather app to see if you need a jacket. Hopefully Apple is taking notes.

Do you use a good weather app that shows live temp on your home screen? Have you tried Fahrenheit?
