Yahoo announced that it will launch a new mobile service called oneConnect by this spring which will offer integrated services for email, instant messaging and social networks.

According to Marco Boerries, executive vice president for Connected Life at Yahoo, Its open architecture means users and other companies can eventually add many other applications to it.

"The key driving force in opening up the platform is putting content into the device. No company can create these ecosystems alone. We have to be open," Boerries said.
