According to May numbers from analytics service StatCounter, Opera is once again the most popular mobile browser in the world, narrowly overtaking the iPhone's built-in Safari browser. Of all the webpages that were loaded in mobile browsers in May, Opera had a 24.6% share to the iPhone's 22.3%. Nokia came in 3rd with 17.9%.

Opera started the year ahead of the iPhone browser, but Apple's product passed it in February. Although they're both mobile browsers, we're comparing two very different products here.

Opera is supported on a huge number of devices from different mobile carriers worldwide, while Safari only runs on the iPhone. In effect, the competition doesn't tell us as much about which browser is the better product as it does about how popular the iPhone is compared to other devices.
