The Milestone Blur is a very beautiful lockscreen theme for Android devices running MIUI GB and ICS ROMs. The theme has been made by Kingz Cheung from the Chinese forum. It is a slide-to-unlock kind of theme. Just slide the screen from the lock icon to right side to unlock device. A semi-transparent mask slides to show you a beautiful background.
The Milestone Blur LS theme is compatible with all MIUI devices with any screen size. I have tested it on my Galaxy S2 and S3 both. Needless to say, the theme has been translated by me as usual before being posted here.
