Land of Droid: Android Apps – Android Phones – Android News – Android 
ICS is a beautiful version of Android, and so is MIUI. But what if there isn’t a MIUI rom for your device, or you’re too scared to root? Well the MIUI team have released the launcher as an app for any ICS user to install. Just download the apk and give it a install.
What are you waiting for?
