For those of you not in the know, MIUI is the Chinese customized version of Android. This ROM combines the goodies found on Android devices and the smooth and beautifully designed user interface of iOS devices, resulting in a more powerful ROM for your Android phone.

This ROM was made to be used on Nexus One and HTC Desire but, due to its improved performance, developers have ported an English version of this ROM to other Android phones such as the HTC One S.

Developer linds6630 has shared a MIUI 4 ROM, based on Android 4.0 Ice Cream Sandwich (ICS), for your HTC One S, so you too can enjoy the performance of MIUI.

Take note that this ROM is not yet in its final build and you may notice malfunctioning features such as the camcorder.
