Phone company Motorola Inc is planning to sell web-enabled mobile phones that feature easy access to Google's search engine by clicking on a button on the phone's keypad.

Motorola, the world's second-largest maker of mobile phones, said in a statement late on Thursday it will integrate a Google icon on to certain internet-optimised handsets that will be distributed starting in the first quarter this year.

Financial terms were not disclosed and Una Kent, Motorola spokeswoman, said she could not give any specifics on what model phones or which operating systems the button will be built into.

Marco Boerries, senior vice president of Yahoo's Connected Life division, said Motorola is also working with Yahoo Inc to bring Yahoo Go Mobile, a mobile version of Yahoo's search and content, to those phones.

Scott Durchslag, vice president and general manager of Global xProducts for Motorola's mobile device business, said: "Many of our customers have been asking for mobile devices integrated with their consumers' favourite online search services.

"Our relationship with Google provides an opportunity for us to offer a high quality mobile search experience - one familiar to and loved by millions of users across the globe."
