XDA member echoside1313 has again released an update of this Echo v4 theme for MIUI ICS. The theme now comes with another variant. Now you can enjoy the same theme in blue and black version. The theme is very beautiful and impressive. Though it does have some bugs here and there, you can still give it a try. Most bugs are due to lack of 100% theme compatibility of the MIUI ROM itself. Download the theme and copy it to MIUI/Theme folder on your device. Then apply from theme manager and reboot device.
