While waiting for MDJ FroYo Glacier v2.0, another xda-developer, motoman234 came out another version based on T-Mobile myTouch 4G. It is a nice Android HTC HD2 ROM to try out while waiting for Android 2.3 Gingerbread ROM. Most of the things are working and you might need install Superuser application to gain root access for your applications. And I just noticed that the camera has face detection function (might be ported from HTC Desire HD).
