A leak on Saturday has signalled that Microsoft is backing away more permanently from the Kin One and Two. The platform's Kin Studio online backup and sharing service will shut down January 31, less than a year after it went live, and will take away nearly all the features unique to the two phones. While e-mail, web browsing and Zune Pass streaming over Wi-Fi will still work, WPCentral's copy of a memo has the home screen social network updates (Kin Loop), direct Facebook updates, Facebook media sharing and the RSS reader will stop working.
