I have the Miro 2.0 theme on my S2 9550. I love the theme with the possible exception that it is not for lefties.
When you bring up the slider of running apps, the label associated with the icon will appear on the left side, which is under the hand of a left handed person.
On the Home screen, hovering over an icon displays a label for the icon at the center bottom of screen. This works if you are using the top two rows. If you go to the bottom row, the label should pop to the top of the screen.
