It works great and its free!
I rooted and uninstalled CityID. Between the force nag and then the ridiculous monthly price I got rid of it. But I kinda liked the feature so I found an old thread about City Caller ID which was a one man app which was sued by a large company to make $2.99 month from CityID.
