It's old news to a lot of BlackBerry owners, but for the AT&T faithful, the OS 4.5 update has been a loooong time coming. The download is now available for all AT&T BlackBerry devices.

Just in case you don't know, the update adds full HTML email, better web browsing, Office doc editing, remote server search, media player upgrades and more—so it is definitely worth getting right away. On a related note, Sprint has enabled BlackBerry users running OS 4.5 to send and receive MMS (text messages with embedded media). Its a banner day to be a Crackberry addict.
