The Nokia 5800 XpressMusic just got a firmware update to version 21.0.110 . Its previous firmware was 21.0.025.

The 5800 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 Honk Kong Product codes at the time of posting, but no doubt it will be avilable across all regions and product codes soon.
Remember you can update using the 5800’s OTA (Over-The-Air) feature, or if you prefer you can download Nokia’s Software Updater application to update your 5800 on your windows PC.
There’s no actual changelog out yet, but we will update this post as soon as we find one. Apparently this update brings speed improvements, and faster web browsing.
[Much Thanks to DailyMobile for the find]
