Microsoft Corp. doesn't appear to be a fan of Windows Phone 7.

On Thursday, the software giant said it was launching a social shopping service called Deals that would work with its Bing search engine. Deals also runs on mobile devices, such as Apple Inc.'s iOS and Google Inc.'s Android operating systems, so shoppers on the go can make sure they're getting the best price available.

One curious omission: Deals doesn't work with Windows Phone 7, the latest version of Microsoft's mobile OS.

Microsoft acknowledged the issue on its Bing Community blog. A post signed by "the big team" thanked users for their feedback but said WP7 wouldn't support Deals until the phone software is updated.

WP7's failure to support Deals comes as the world's largest maker of computer software scrambles to respond to a computing market that is rapidly shifting to mobile devices. While many of its products, such as the Windows operating system and Office suite of productivity software, rule desktops and laptops, the Redmond, Wash.-based company has made little headway in the world of smartphones and tablet devices.
