Creative Studio is a great and simple way to quickly edit the photos you shot with your Windows Phone 8 powered Nokia Lumia 920. You can choose from many attractive photo filters.
If you are the kind of person you want to read what has been changed before updating an app you can disable the auto app update setting. Or enable if you want updates fully automated.
Really great and free service where you can chat using a bunch of services like Skype or Google Talk within your web browser, meaning you don't need to install anything on your computer.
