Hackers using iPhones but secretly lusting after the HTC Hero have managed to bridge the gap by skinning the iPhone with the Sense UI.
You get an HTC-a-like clock, a weather widget from Yahoo just like on the Hero, and movable icons at the bottom, as well as a quick launch bar.
To add to the iDroid experience, the developers have also brought in the menu tab, meaning you can drag it across the screen to access the iPhone menu (although with the quick launch bar still intact).
And to take things even further, the dial pad has been re-jigged to use the Hero's larger buttons, so fat-fingered iPhone users can now rejoice.
Admittedly you have to have a jailbroken iPhone to use it, but for everyone secretly wishing their Apple device has the superior functionality of the Android interface, this theme could be the one for you.
Check out the video of the device in action and head on over to Redmond Pie if you want to risk your phone and take the step by step instructions:
