Look, we know that jailbreakers and developers love to show off - but we can't help but look at this and think: "What's the point?".
We mean, if you like the Windows Phone 7 OS that much, then there are plenty of handsets out there running it natively, without the need for jailbreaking and installing a custom theme on your iPhone (ten handsets to be precise).
But hey, someone's gone to a lot of effort and it does look pretty good. Although why the Safari app has an Internet Explorer logo is beyond us - that's just taking it too far.
The theme is called OS7 and requires Backboard from Cydia.
Weirdest iOS theme hack yet? You betcha.
