Well almost two Googlers - one is senior staff research scientist at Google and another is third year PhD student doing research remotely at Google.

You can find document at PhD student's site at [maryamkamvar.com...]

Document is titled "Deciphering Trends In Mobile Search" - it's a PDF document. Be mindful of Zero Day PDF Security Hole [webmasterworld.com]. I opened it at nothing bad, that I can see, is happening but YMMV...

We analyzed data from more than 1 million page-view requests randomly sampled from Google logs during a one-month period earlier this year. The requests were anonymous; we maintained no identifying information that could associate searches with users. To eliminate confounding factors between different carriers, we restricted our examination to a single US carrier. To differentiate among computers, PDAs, and cell phones, we looked at the browser’s user agent sent in the HTTP request. Unless otherwise noted, the mobile statistics we present pertain to cell phones.
