What makes you think the 'official" build is not going to be the test build with an official stamp? I'll be surprised if its much different. Regardless 2.2 is working fine for me so I'll wait to our guys get their roms going and move to one of them when they get them available. For me both enomther and cm were every bit as good as 2.2, some pluses and minuses either way, but the thing I want is froyo after they get done with it. Thats a win.
This would have probably been better off in general but then its already been posted there....
