It hasn’t been all that long since Koush initially teased fans of ClockworkMod Recovery with the touch-based version, but back then it wasn’t able to download. That all changes today, if you have yourself a Samsung Galaxy Nexus or Nexus S, that is. The recovery option is available now to download in its Beta form, if you’re willing to give it a shot.
As for variations of the devices, you’re looking at both the CDMA- and GSM-based versions of the Galaxy Nexus. The Nexus S, though, is for the GSM variant only. Go ahead and head through the source links below for more information and to get your download on.
