San Francisco :  Microsoft Corp has pulled the plug on a new generation of smartphones less than three months after unveiling the devices that were part of its efforts to catch-up with Apple Inc and Google in the fast-growing mobile market.

Microsoft said on Wednesday it had cancelled plans to sell its ‘Kin' phones in Europe this autumn. The company added the internal team working on the Kin phones would be combined with the group working on Microsoft's forthcoming Windows Phone 7 software.

"We will continue to work with Verizon in the United States to sell current Kin phones," Microsoft said in an emailed statement.

The move underscores the challenges facing Microsoft, whose software is used on the vast majority of the world's PCs, as it strives to adapt to consumers' growing taste for handheld internet-connected gadgets like smartphones.

In April, Microsoft said it was shelving an internal project to develop a tablet PC similar to Apple's iPad.

Restructuring

In May, Microsoft reorganised its mobile phone and video game division, announcing that longtime Microsoft executive Robbie Bach would retire and that the senior vice-presidents in charge of phones and games would report directly to chief executive Steve Ballmer.

Ballmer is "looking at the [mobile] business, seeing what's making money, what makes sense to do going forward," said Matt Rosoff, an analyst with Directions on Microsoft.

The Kin phones represented software giant Microsoft's first foray into designing its own phones. The two Kin models featured built-in internet social networking functionality as well as Microsoft's Zune digital music player and were aimed at savvy young phone users.

Microsoft began selling the Kin phones with Verizon Wireless in May. Verizon Wireless, the largest US wireless operator, is a joint venture of Verizon Communications and the Vodafone Group.

Application setback

But Rosoff said the phones lacked certain key smartphone functions, such as the ability to install software applications, yet had wireless data service plans that were priced comparably to more full-featured devices like Apple's iPhone.

The Kin was also based on a special Microsoft software called Windows Phone OS, even as Microsoft prepared to release the new Windows Phone 7 mobile operating system. Smartphones running Windows Phone 7 are expected to be available this holiday season.

"Windows Phone 7 is the real mobile strategy," said Rosoff.

"The fact that it [the Kin] was ever released in the first place was a mistake. When they went with Phone 7, they should have quietly killed this project."

Verizon Wireless spokeswoman Brenda Raney said that the Kin remains an important part of the company's "portfolio."
