I listen about Mobile Web Analytic but i think it is more beneficial for mobile site. Any one tell me that google analytic can show page views, hits, visitors, geographic locations additionally includes mobile specific information such as: mobile device, mobile network operator, country, language and a unique user ID.

As far as I know you can find all of this out by using Analytics or at least most of it. My sites are geared to convert all mobile traffic once a browser is detected and it displays in Analytics.
I think there could be some possible issues with certain handsets not supporting the java tracking code- and if so, that session wouldn't be tracked.
