Guess what? Big surprise. Opera's Mini browser is apparently pretty popular. In Opera's latest "State of the Mobile Web" report, we learn that most Opera users (worldwide) have a Nokia phone, but nine of the top 10 phones for Opera Mini in the U.S. are BlackBerrys. Opera also pointed out that its users pushed 46.7 million MB of data for operators. That's a lot of mobile data, people.Opera publishes this report about the mobile Web pretty regularly. This time around, it chose to look at the types of phones that are using its browsers worldwide. The results are pretty interesting.

"People want the Web on their phone regardless of the type of phone they have," said Jon von Tetzchner, CEO of Opera. "Our list of top phones shows both smartphones and feature phones, which is a testament to the versatility Opera Mini provides. Additionally, it proves that given the right experience, many more people will use the Web on their phone. Accessing the Web on your phone is not a luxury limited to who has the most expensive phone model."

Around the word, the 10 most popular devices are: Nokia N70, N73, 6300, the Sony Ericsson K750i, the BlackBerry 8310, the Nokia 6233 and 6600, the Samsung E250, the Sony Ericsson W810i, and the Nokia 5300.

In the United States, where Nokia has a depressed presence, the results are entirely different. The top 10 phones are: the BlackBerry 8310, 8100, 8830, 8330, 8130, 8320, 8300, the LG LX260 (where did that one come from?), and the BlackBerry 8700 and 8800. Basically, all the current Pearls, Curves, and 8800 series BlackBerrys are seeing heavy Opera usage.

Some other stats compiled by Opera show that usage is increasing. Opera Mini users viewed more than 3.2 billion pages in June. In June, each person using Opera Mini viewed 223 pages on average. Since May, page views have gone up 9.4%.

The top mobile Web sites in the U.S. are: Google, MySpace, Facebook, Wikipedia, Yahoo, the New York Times, GameJump, Accuweather, YouTube, and My.Opera.Com.

In total for the month of June, 14.5 million Opera Mini users generated more than 46.7 million MB of data for operators worldwide. Since May, the data consumed went up by 8.4%. Data in Opera Mini is compressed up to 90%. If this data were uncompressed, Opera Mini users would have viewed more than 311 million MB of data in the month of June.

In other words, a lot of people are using Opera to browse the mobile Web, and they're doing it a lot.
