iOS Clone??

Is this video MIUI? If so how how I get my G2/DZ to look like this? Right now I just have an iPhone theme for MIUI, but its nothing compared to this.

That's definitely not MIUI. Did you read the comments for the video? it's a Chinese OS running on a fake Chinese HTC knock-off with an elaborate iOS skin. Someone in the comments went through a list of things that are different between that and iOS, so it's not really iOS. And the OS it's running on is closed source. You're going to have to settle for the iPhone theme you're using or buy an iPhone.
