Pew Internet has just released its latest report on mobility and the internet. In short, the findings demonstrate the continuing explosion of mobile Web use.

As of May 2010, 59% of all adult Americans go online wirelessly. Pew's definition of a wireless internet user includes the following activities:

• Going online with a laptop using a wi-fi connection or mobile broadband card. Roughly half of all adults (47%) go online in this way, up from the 39% who did so at a similar point in 2009.
• Use the internet, email or instant messaging on a cell phone. Two in five adults (40%) do at least one of these using a mobile device, an increase from the 32% of adults who did so in 2009.

Taken together, that's an increase over the 51% of Americans who did so at a similar point in 2009.

Cell phone ownership has remained stable over the last year, but users are taking advantage of a much wider range of their phones’ capabilities compared with a similar point in 2009. Of the eight mobile data applications we asked about in both 2009 and 2010, all showed statistically significant year-to-year growth.
