For those that dont know, Windows Phone 8 features the ability to backup your high resolution pictures and videos to your SkyDrive account. However, this feature was only available in limited markets. Not anymore.
Microsoft has announced in an official blog post that all Windows Phone 8 users, no matter their location, may now use this functionality. "Today I am pleased to announce that we’re making the ability to back up full-res photos and videos available everywhere. (We just started to light this up, so be patient if you don’t see it right away. The change could take a few days to roll out around the globe.)" Microsoft stated.
In order to use this feature on Windows Phone 8, simply tap Photos > More > Settings > SkyDrive. Then tap Best quality to upload your photos or videos in the highest resolution. This feature requires a WiFi connection, in order to save you from an expensive internet bill. For those wondering why it took so long, Microsoft "deliberately" took things slow and "planned a staged roll out of the feature" due to this feature involving a lot of data.
