The good folks at miui.com have just released their first rendition of their quite popular ROM for the Nexus S. Unlike other devices supported by MIUI developers, the Nexus S is the first to get Gingerbread. Other devices such as the Nexus One and HTC Desire will probably see Gingerbread in 2 weeks from today.
So if you have the Nexus S and want to give this a go, you can pick it up at the following link. Currently it is still in Chinese (but 100% deodoxed) with English language packs to follow later today. We will update the links once it's released.
All credit goes to MIUI.com and Miui-Dev.com for all their hard work.
