Oliver Starr writes that Mobile 2.0 is not Web 2.0.
Whereas Mobile Web 2.0 is all about the advanced capabilities associated with a specific subset of systems within a mobile device and particularly centered around some kind of web enabled interface Mobile 2.0 is more about the entirety of the device and its myriad and highly differentiated possibilities for interaction with the end user. In a nutshell, Mobile 2.0 is the superset of life altering functionality conveyed by a functioning mobile phone to that phones owner.
Mobile 2.0 is not device dependent. There is no measuring stick of functionality that is a determinant as to whether or not a mobile phone is or is not a Mobile 2.0 device. All functioning phones today are Mobile 2.0. It isnt what the phone does, so much as what is being done with the phone that has lead us to Mobile 2.0. This definition has the advantage of extensibility – a developing country experiences Mobile 2.0 by virtue of the changing socio economic status of those that own phones. In Japan or Korea Mobile 2.0 can be seen in the development of entirely new forms of entertainment oriented content for display on mobile devices and in the US we can see the birth of Mobile 2.0 in the roll-out of presence enabled services and phone-based navigational services.
