Some of the first Windows Mobile 6.0 phones to hit the market will include the Opera browser, as well as Microsoft's own Internet Explorer Mobile.

Microsoft's Windows Mobile 6.0, launched this week, includes Internet Explorer Mobile, but handset makers have decided they want a choice apparently. Motorola's Q, and phones from HTC Asus and Toshiba will include Opera Mobile, said Jon von Tetzchner, co-founder and chief executive of Opera, at the 3GSM show in Barcelona.

The handset makers decided to add the Opera browser to give people the best browsing experience on their big expensive screens, said von Tetzchner: "People do want a quality browser when on Windows Mobile," he added. Opera renders Web sites to fit inside the area of a mobile phone screen, and is designed to display sites faster than competitors', he said.

In addition to Opera Mobile, the company also offers Opera Mini, a free browser that works on most Java-enabled phones. It communicates with a server hosted by Opera or a mobile operator that strips down Web sites for quicker, less data intensive mobile browsing.

Mozilla also offers a mobile browser called Minimo that hasn't gained much traction in the market. Nokia has used Opera browsers historically but is now primarily using a browser it developed internally.
