What’s a Saturday without a little BlackBerry OS love? We’ve got some screenshots here of the upcoming 4.3 OS update courtesy of a BlackBerry Curve with the OS update installed. We don’t have an official spec sheet here, so details are limited to the information present in the screenshots. That said, unless anything significant is missing, we’re inclined to peg this as more toward the "evolutionary" than "revolutionary" side of things. Upgrades of note? Voice Notes have been integrated into the media player, OTA wireless upgrades are now possible (weren’t they before?), and the UI of the email and address book apps seem to have been overhauled. Not much else to report here, save for a couple of new menu items. Check out the full set of screenshots after the jump!
