I had it for about a month and I finally got sick of how it handles the radios, (not good) and that was the final straw for me. The transitions are SMOOOOOOOTH, but that was about it for the good stuff. Lacked a few things I like from other roms, and it uses Launcher as a home screen. Not a fan.
It's a good rom. To answer your question its 2.3.7 and about 30-60 days old. I ran that for awhile and then went to work shed's rom which is fairly similar. Liquid used LP+ and Work Shed used Go Launcher.
Just went back to infected rom as that is the best sense roms for me. Now i am just waiting on them to crack data on the ics roms or for a good rom based on the mr4 leak.
