Sure, it’s been on the BlackBerry download site for a while now, but AT&T has finally started to announce the arrival of OS 4.5 for three of its handsets: the 8820, 8320 and 8310. We’re guessing that AT&T is subtly trying to say that if you’re device isn’t covered there is a Bold with your name on it at your nearest AT&T store. That or sit tight and wait until we get our act together (tip: Delete vendor.xml and you can use any carriers OS builds on your BlackBerry so long as it’s designed for the same device).
Anyway, OS 4.5 has a heck of a lot of improvements over its predecessors so if you don’t have it you owe it to yourself to start the process here.
