SkyDrive is at the heart of Windows Phone 8 but there may be some people who are looking to be able to views all of their cloud stored files in one place. With the bump of SkyDrive to version 3.0, it is now ready to roll on Windows Phone 8. In this latest version you are able to search files and folders. Photos get new options in regards to upload and download size and you see a huge improvement in performance. This version is only available to those with a Windows Phone 8 handset. Sorry Windows Phone 7.5 users.
