Iphone Application Icon Over Here

I need a new icon for my iPhone application, "Over Here".

The application allows you to email your current location as a Google Maps link to any of your friends, allowing them to locate you. So for example, if you're meeting a friend in a restaurant they've never been to before and can't find you you can send them a Google Maps link of your current location to them and they'll be able to see where you are on their iPhone.

There are a growing number of applications that do this. Over Here was amongst the first. Despite having what I believe to be the best feature set amongst these applications I need something extra to differentiate it.

The current icon for the application is one I knocked together rather quickly, but is probably the best I can do. You can see it if you search for "Over Here" in the iTunes Apps Store.

I would like a new icon for the application that is simple, in a similar style to the icons for the applications included with the iPhone but different enough from the Maps icon.

Apple require a 512x512 pixel image and a 57x57 pixel icon. The icon is the most important part, but a similar large image that is styled like the icon, but would probably include a larger version of the icon and the words "Over Here" is needed too.
