This Firmware brings updated versions of several applications such as Browser, Mail for Exchange, and Shazam etc. for Nokia X6. Whereas Nokia X3 gets improved battery charging notification and ring and alert tones.  Also it is now easier to register your device with Nokia’s Ovi Music Unlimited (previously known as Comes With Music) using pinless activation.

You can update your Nokia X6/Nokia X3 firmware via OTA (Over-The-Air) or via Nokia’s Software Updater application , Nokia Ovi Suite on Windows PC. The Nokia X6 does have UDP (User Data Preservation), but its always a good idea to backup all your personal data before updating the  firmware.
