This is the work of Dimos (Darkspear-H), and if you want to Blizz up your own phone, the files to do so are at ModMyiPhone.com. I particularly enjoy the Phone icon being a hearthstone. A common conception on RP servers is that the hearthstone is what enables us to communicate in chat channels, serving as some sort of radio-like device. I don't know if this is what Dimos was going for, but it pleases me either way. The Safari icon is also an uncanny match -- does anyone know what that icon is used for in-game?
