it's a bit big...
(looks good though)
Font looks really cheesy.
Personally, I think the icon looks ok at 512px (needs a better mask though!) but bad at 59px (or whatever the iPhone's odd icon size is) ... At that low resolution, you can't even tell that it's a globe! The multi-colored continents are impossible to distinguish, and the text doesn't stand out enough (try a small white glow around the text to isolate it) ...Better, worse?

You might try something that'll fit in more with the other icons, perhaps a squared globe/map with the text running across? Simple is good.
