Apple Touch Icon: Is it possible to update on the favicon on a web-mobile app for iOS?

Is it possible to push update on the favicon (ex. apple-touch-icon.png) on a web-mobile app for iOS? I mean, I saw a weather app that uses the actual app icon to update the temperature...

is it possible in your html5 web app (saved to your home screen)?

to be precise i just saw it working on this web app: pattern.dk/sun and their icon displays exactly the realtime temperature, is that just a trick maybe??

UPDATE The icon doesn't really update in real-time but only when you open and closes the app. still interesting though.

As of iOS 7.1 the web app icon seems to update even if the filename is the same.

I think I found the trick

i'm adding a time stamp to the icon filename like:

    <link rel="apple-touch-icon-precomposed" href="favicon.png?<?php echo $date->format('U'); ?>" /> 
//this is a PHP piece of code but you generat a timestamp in any way you want

so anytime you open the boomark the icon app refresh itself
