Monthly stats showing which handsets are most popular for internet usage, and which drive most ad requests, have come in from Opera and AdMob.
You can see the AdMob stats and metrics as a PDF here, as well as a blog discussion of them here.
Highlights include the revelation that smartphones drive three times as much usage as feature phones, and that the same smartphones over-idex highly when it comes to accessing html pages.
Opera’s report information and discussion of the results can be accessed here. Opera highlights the fact that in April 2009 it had over 23.4 million users, up more than 140% compared to April 2008. Opera Mini users also viewed nearly 8.7 billion pages in April 2009. Since April 2008, page views have increased 249%. Last month, Opera Mini users generated more than 151 million MB of data for operators worldwide. Data in Opera Mini is compressed up to 90%. If this data were uncompressed, Opera Mini users would have viewed up to 1.4 PB of data in April. Over the previous year, data traffic is up 295%.
