The solution should show these basic statistics:
- Unique visitors per day/month/year
- Page views per day/month/year and per visitor
- Mobile phone types
- Countries of visits
- Mobile operators per country and wap or Internet APN
- Referrers (not very well supported on older phones)
My personal opinion is, that there are no Mobile Analytics project simply because everybody is waiting on Google.
If you start this kind of project and Google will launch it one month later, you are doomed and you can maybe close your project if you don't find any value added services, which Google is not offering. I believe, that good solution could be premium (for example statistics about operators) and the whole project can be profitable next year (if Google will not do it).
So dear Google, when we can start looking forward your mobile version of analytics?
