Another day, more major firmware updates from Nokia, this time for even older devices, again rolling Maps 3.3 with free navigation into the ROMs - excellent to have. v500.21.009 for the two year old E71 and E66 also brings the very latest editing version of Quickoffice and latest Ovi Store client, plus bumps to Music player and to Lotus Notes Traveler, among the usual minor improvements and fixes. 

PS. the E63 has now also received this update.

Note that v500 is for the unbranded device in most markets. Network-branded/locked handsets may have custom firmware that will take longer to be updated and approved.
