The X6 does have UDP (User Data Preservation), so while its always a good idea to backup all your data before the firmware update, none of your programs or data should be affected with the update.
The update has only come to certain AsianProduct codes at the time of posting, but no doubt it will be available across all regions and product codes soon.
Remember you can update using the X6’s OTA (Over-The-Air) feature, or if you prefer you can download Nokia’s Software Updater application to update your X6 on your windows PC.
The Official Changelog for this firmware is:
This software release includes updated versions of several applications, such as Browser, Mail for Exchange, and Shazam. This release also comes with usability improvements, for example, in video calling. To get this software through your device, select Applications > Software Update, and choose the software you want to update. Alternatively, this software release is available through the Nokia Software Updater.
