Here are some things I've noticed: 1. When you exit out of an app (with sound/music), the audio will fade, instead of just cutting out. 2. When viewing a particular Artist in the iPod/Music app, the top left button states the name of the artist, instead of the word "Artist". (Only works when you have more than 1 album) 3. The iPhone doesn't vibrate when you take pictures anymore (Or maybe it's just my device/FW) 4. The icons for the iPod/Mail/Weather/Text/Phone app are changed.
