Finally someone found how to run Android in iPhone!

What will you do if you have an option to run Android OS in iPhone?
Someone managed to build a case that can hook with iPhone charging point and run Android operating system. This will give the user complete experience of Android. But the founder of this iPhone Android case does not have plan to sell commercially. Might change his mind in future for better offers once the product is stabilized.

Here is what the team from http://www.engadget.com/ says about Android case:
It involves strapping a tiny Android device to the back of your iPhone.

Familiar with cramming one operating system into somewhere it doesn't belong, developers at Tendigi have just created a homemade iPhone case that lets you run Android on your iOS smartphone. (Well, kind of). Fortunately, because of the Android Open Source Project, it gave Nick Lee the freedom to clone the mobile OS and build his own local hardware. Before he went that far, Lee decided to test the concept -- streaming Android across to an iPhone through a cable -- with a Nexus 5. He needed tools that could communicate with iOS, as well as services that let USB cables play nice with an iPhone. Lee also crafted software that transmitted what was happening on the Android devices' screen to the iPhone, while also send touch-input back. The next challenge: cramming it all into an iPhone "case". See it working after the break.
He then made his own tiny Android development board, linking it to the soon-to-be franken-iPhone and its own power supply, prototyping and 3D-printing an enclosure to house it all and attach to the iPhone. It's not the prettiest case, and really you're 'streaming' Android to your iPhone screen, but it's the man-hours thought that counts, right?
The report states that Lee managed to develop this product in 45 hours flat. He has no immediate plans of selling it commercially, but may change his mind if interest piqued, and would think of investing more time into building a sleeker case.
