As promised back in mid-February, T-Mobile has launched Yahoo's oneSearch mobile search engine, replacing Google as its primary search partner in northern and central Europe, 3G.co.uk reports.

OneSearch results appear on a single page and are grouped by category, something that's supposed to remove the pain of slogging through pages and pages of links. The search technology is said to "understand" the intent behind the query and returns information it deems relevant.
