A few days ago, all variants of the Galaxy Nexus got the first taste of ClockworkMod 6. Now it's available for the Nexus S/4G and the Nexus 7, in both standard and touch varieties.
This new version of CWM brings a host of new features, like faster backups, incremental backups (yay!), a fix for restores over 2GB, and some UI tweaks.
As always, you can either grab the downloads directly from the ClockworkMod site or flash them directly from ROM Manager.
