I connected my Nokia 6267 (RM-210) to my PC this morning and what do you know Nokia PC Suite alerted me of a new update for my mobile. I downloaded Nokia Software Updater 1.4.9 [a new version]. While waiting for the update to finish downloading and installing [it's 37.2Mb] I poked around the Nokia site and saw Nokia PC Suite 7.0, so I downloaded that as well.
I have no idea what the FW includes but I'm flashing anyway. Will report back if I notice any glaring differences after the update.
