9to5Mac make has made a pretty interesting discovery, noticing that Apple has changed some of the icons on its official iOS 7 page. Notable changes to the Weather, Passbook and Reminders icons can be seen. The changed icons can right now only be viewed via a mobile device. Passbook and Reminders only have minor colour changes, but the weather icon removes the sun and clouds and replaces it with temperature which could potentially be a live icon, much like the clock icon in iOS 7.
We have no idea if these are older designs placed on the site by mistake or Apple are actually listening to users. We guess we'll find out in later betas.
