Yahoo! unveiled a mobile bookmarking tool, which lets users track favorite Web topics on their cell phones. Called onePlace, the company hopes to launch the application in the second quarter of this year.

Similar to other bookmarking tools, onePlace promises to allow users to keep track of links, news feeds, search results, e-mail chains, videos, photos and more, that are updated whenever a customer clicks on a favorite topic. Users will be able to gather their favorite online sites by synchronizing their PC favorites to their phone or by bookmarking them directly on the handset. And like Yahoo!’s OneSearch, display results show actual information rather than Web links.

“Over the last three years, we have aggressively executed on our mobile strategy to deliver innovative and indispensable services to consumers globally and become the starting point for the most users. With the introduction of Yahoo! onePlace, we are announcing the next essential component to our mobile product line up,” Marco Boerries, executive vice president of Yahoo!’s Connected Life, said in a statement. “Yahoo! onePlace is where users will be able to find what matters to them the most, no matter where their interests, passions and information come from. Yahoo! onePlace will provide mobile users with a rich and dynamic content experience.”

Users will be able to access onePlace through carriers who have deals with Yahoo!, or download it directly from Yahoo!
