Anyone has any idea what the play/rewind/forward and signal thing? It doesn't has that when WP7 first launch then don't which update it appears there and I've no idea what's that for...

I don't get the idea of getting this. Why not go for invisible shield instead? Don't you want to show off your Nokia color instead of changing it into some carbon body? It's just like those people go stick the carbon sticker on their car bonet... Anyhow, it's just my 2cent. Myself got the invisible shield from ebay, basically works the same and yet I can show the true color of my phone although it's just white color
