Following on from availability for the Nokia E52, now available over the air is v34 firmware for the Nokia E55 as a 620k download, a minor bug-fix update but worth grabbing anyway as it doesn't affect any of your apps or data. It's also available as a full firmware image via Nokia Software Update, but over the air is so quick that it's the way to go.

To check your firmware, type *#0000# into the homescreen - if you don't see v34 for your branded contract device then you'll have to wait for your network operator to approve the update.
