Microsoft is telling the world+dog that its Bing browser is going to be deeply embedded into the Blackberry.

Shy and retiring Microsoft Chief Executive Officer Steve Ballmer made a characteristically understated appearance at the annual BlackBerry World trade show in Orlando, Florida Bing will be deeply integrated into the devices, creating “unique experiences for millions of BlackBerry customers. He didn't say that they would be good experiences, just unique ones.

Ballmer said the partnership will be ready in time for the holiday shopping season later this year. The RIM partnership also advances Microsoft’s efforts to expand in mobile devices, a campaign that includes a pact with Nokia, the world’s largest mobile-phone maker by unit sales.
