Tips have been flying in and it looks like AT&T has released OS 4.6.0.304 for the BlackBerry Bold 9000. This isn't the grand 5.0 update we may have been waiting for, but an official OS update regardless. No word on the changes/updates in this version, but if you are still rocking an older OS version you may want to give it a go. Head over to the BlackBerry Software Download page to get going.
