It also wouldn't hurt to change the icon as well. The calendar app's icon does this.

+1 for changing the icon based on the primary location. I want this feature much more than location-awareness. (Jailbroken iPhone has icon-changing weather app)

Is it (technically & politically) possible to make the App Icon change based on App State? I thought that was restricted / impossible a while back.

Not if you're the developer of the built-in weather app.

Since the app bundle is signed, and the icon is inside the app bundle... no, but Apple can cheat for their own apps: Calendar's icon always shows today's date. Clock and Weather could update continuously too. For third party apps, I'd like my stopwatch to keep updating it's icon in the background, and one of my apps could do with it too.

A more serious problem is not being able to update Default.png, so if your app loads the last view the user had, it's hard to make it seamless.

edit: I meant changing the icon based on the current weather at primary location, which should be the current location by default

The "Weather Icon" app from Cydia accomplishes this. There's a similar WinterBoard extension for the clock ("LiveClock"). Both work wonderfully.

(Edit: it changes based on the weather and the time, not based on geolocation.)

Move somewhere where it's never 73 and sunny. That way you'll never be confused.
