Z4root is a application that help you to root your Android device
To do that you would have to root your phone. The simplest way to root your phone is to use Z4 Root
A very basic Z4 would be about $47,000 for a 2011 Z4. Like many other cars you can buy different "editions" of a car. In the BMW Z4 there is a Z4 sDrive30i ($47,000+), Z4 sDrive35i ($53,000+),Z4 sDrive35is ($62,000+). The same goes with the Ferrari. I can't give you the exact differences but it would be $100,000+
Be careful about rooting you device because it voids the warranty but, if you don't have one or don't care here's how. To root your Android device go to the Android Market and download an app called 'Z4 root'. This app may not root all devices but has a large selection of devices to choose from.
