"A new firmware update, version 31.012, is now available for the Nokia E52. The update is currently only available via Nokia Software Updater (PC). We've not noticed any major changes, but a number of bug fixes and small version updates to built in applications (Web, Email, Music Store, Maps) are included. The phone's noise cancellation parameters have also been updated, which should improve audio quality of calls. Please let us know about your experiences in the comment thread." via allaboutsymbian.com
