It looks like MIUI 4 – the beautiful custom ROM based on Android 4.0 – is now available for the Amazon Kindle Fire. The ROM isn’t quite the same as its phone counterpart in terms of user interface yet but you do get a nice package of the many MIUI-specific applications available, including the custom file manager and backup utility.
Both the Android Market and the Amazon Appstore are supported so users shouldn’t have any issue finding the apps and games they need. If the Kindle Fire’s custom user interface isn’t doing it for you and you don’t mind losing all that Amazon integration be sure to give it a shot. You’ll need to be rooted and all that jazz, but you can find everything you need to get started at this link. Happy flashing!
