The layout has changed a little bit, but not much. You have more apps on the pages now.
Other than that there's a new icon and some new settings, like:
- auto updates activated by default for all apps
- auto updates just over Wi-Fi
- auto-add shortcuts
Also I find it snappier than V3.1.5.
I don't know if other Xperia devices got the update yet, but if not, they should get it soon.
