Yahoo has signed a deal to provide mobile search software for T-Mobile in the US.
The two companies announced on Thursday that Yahoo will license its oneSearch system for use in T-Mobile handsets. The search engine will be part of T-Mobile's web2go mobile internet service.
OneSearch will be optimised for the handsets, so that users will be given results not only as links, but as news and other data related to the search query, such as cinema listings for film searches or score updates for sports queries.
"With our innovative products and global partnerships we are a leader in mobile search and are incredibly excited to bring Yahoo oneSearch to more and more users every day," said David Ko, senior vice president of Yahoo Connected Life.
"Together, T-Mobile and Yahoo are providing compelling mobile services, while creating unique opportunities for advertisers to reach the rapidly growing audience of mobile consumers."
The announcement is part of an ongoing effort between the two firms to provide search functions for T-Mobile. In February, the companies announced that Yahoo would power search functions for T-Mobile in 10 European countries.
The deal was seen at the time as a major coup for Yahoo, which beat rival Google for the contract.
