You can update your Nokia E52 firmware over OTA (Over-The-Air) or by using Windows PC applications Nokia’s Software Updater or Ovi Suite . The Nokia E52 does have UDP (User Data Preservation), but its always good idea to backup all of your personal data before updating the device firmware.
There is no confirmed changelog yet, but we’ll update this post if we find one.
Note: It may take some time before the new firmware is available for your region.
