I am looking for a good City, Country State database
It does not have to be crazy detailed, something that has a good coverage of Cities and their corresponding State,Countries in the world will do it for me.
Appreciate if you can point me some links. Thanks
Yahoo! provides a Creative Commons license to its geodata, including unique identifiers (Where-On-Earth IDs) and hierarchical information for millions of places on earth, including cities, metropolitan areas, states, countries and other types of divisions. Much of this data is downloadable and they also have an easy-to-use API.

Although as an alternative, have you considered tapping into the Google Maps API? It's free, and they provide good instructions to integrate your app.
have a cities of the world CSV dataset compiled from the USGS GNIS Server (US) and US NGA GNS Server (non-US), that I have placed into the public domain. Below is a link and metadata of the layout.
Column 1: ISO 3166-1 alpha-2 country code.
Column 2: US FIPS 5-2 1st level administrative division code (e.g., state/province).
Column 3: NGA GNS Feature Description (DSG) code.
Column 4: NGA GNS Unique Feature Identifier (UFI).
Column 5: ISO 639-1 alpha-2/3 code for language corresponding to the feature name.
Column 6: Language script (e.g., latin, arabic, chinese, etc) corresponding to the feature name.
Column 7: Feature name.
Column 8: Latitude coordinate of the area centroid.
Column 9: Longitude coordinate of the area centroid.
