Based on my lengthy explorations through all depths of the Internets, I’m quite comfortable in saying that their probably aren’t too many people out there looking to make their iPhone look more like a Windows Phone 7 phone.
But if, somehow, there is some massive horde out there all clamoring for a WP7-themed overhaul, let them know: it’s here. And it’s actually… pretty dang impressive. You’ll need to jailbreak the phone and install the theme via Cydia — but then you’re free to go about your way, installing WP7-themes on iPhones, singing to cats, eating paint chips, and whatever other crazy things you might do.
