If you don’t want to wait Philips Fidelios media docks for Android devices then you may make it by yourself. You should just follow by this instruction, have some free time and be familiar with electronic and polymorph.
Another way to use iOS dock with Android device is to get the DockBoss+ cable with has iOS connector on the one side and micro-USB + audio jack on another. It’ll cost you around 30 bucks plus delivery.
So, even now we have at least two ways to use Android device as a part of home media system. But personally I’ll wait for Philips Fidelios.
