There are quite a few roundups you can get on the web regarding “Mobile 2.0″ or “Phone 2.0″ or even “Telco 2.0″. Rudy De Waele of m-trends gives regular presentations on Mobile 2.0 at various conferences, as well as blogging on the topic at m-trends. I think his latest presentation is a great introduction to the whole area, and for the most part, it can stand alone, although I know the value is greatly enhanced if you can listen to the man himself run through these slides.
