Rumor: Windows Mobile 6.5 to be unveiled next month

Microsoft CEO Steve Ballmer made "candid" comments in November that Windows Mobile 6.5 would be available in the first half of 2009, and reports are speculating that the update will be rolled out at the Mobile World Congress in Barcelona, Spain on February 16-19.

Ballmer is scheduled to give a keynote speech at the conference, where the revamped Mobile OS and associated services are expected to be unveiled.

All of the new services will be baptized with the "Sky" prefix that Microsoft launched with SkyDrive: SkyMarket will be the Windows Live App Store, SkyBox will be the mobile backup and sync service (think MobileMe, but cross-platform), and SkyLine will be SkyBoxes equivalent for small- to medium-sized businesses, featuring integration with Exchange.
