I fairly know the answer is - No! (based on google search)
But I couldn't find a way around this.
The theme chooser in CM7, also called tmobile theme chooser - is it available as .apk that will work on other gingerbread ROMs?
I tried to use .apk from CM7 nightly to GSF B22, but installation keeps failing.
What will make a ROM compatible to theme chooser? and do we know of any other gingerbread ROMs that can benefit from theme chooser and eventually the themes floating around in market?
