The iPhone 4S iOS Theme for MIUI V4 was in a very raw state when I posted it last time a few weeks ago. The theme has now been heavily improved and the updated version was released just a few hours back. The theme has been made by raykiyang from the Chinese forum.
So, the theme is basically in Chinese, especially the lockcsreen and the messaging interface. I had to spend a few minutes to translate the theme in English. The theme has acquired a remarkable beauty and give you the best (so far) iOS experience on your Android device running MIUI V4.
