Gingerbread Theme for CyanogenMod 6.1
Android 2.3 Gingerbread isn’t going to be released for any device till the Nexus S is launched on December 16 and Nexus One users are also eagerly waiting for the launch along with other Android phone users
A developer at XDA has managed to develop a Gingerbread (Android 2.3) theme/metamorph for CyanogenMod 6.1 users.
This theme looks exactly like the actual Gingerbread UI. You can download this theme to explore more.
It works perfectly fine on my Nexus One with CyanogenMod 6.1 on it. Download links and more info can be found here: Download Gingerbread Theme.
