1-Yes.

2-S4.

3-Not yet.

Cause that's the way aurora team wants it :)

I think is kinda cool.

Use this launcher:

http://xdaforums.com/showpost.php?p=63288832&postcount=7466

and that's it, you got shadows.

Badges launcher for i9500 doesnt have shadows btw. Only those with grid.

Most likely that's not an i9500 screnshot.
