Seems as though the Windows Phone 7 focus is going a step further with the planned closure of the Windows Mobile web accessible Marketplace on July 15th 2011. Fear not if you still use this platform since you'll still be able to purchase and download apps from the Marketplace on your Windows Mobile Phone.
My Phone is also scheduled to be discontinued on August 7th 2011, which will affect those who rely on this service for backing up your device content. Also starting on the 7th, Microsoft will begin transferring your My Phone content to SkyDrive. You'll be able to access this storage with the LiveID you used to register for the My Phone service.
Be cautious however, videos, music, documents and favorites will not be moved to the SkyDrive and will need to be manually backed up to your local machine. On October 6th 2011, the My Phone website will cease to be available. Microsoft will keep your content (on CD and DVD) from the service for one year, which can be shipped to you upon request by October 5th 2012.
