If you are an owner of the RIM BlackBerry Bold 900 on the AT&T network, you may like to know that it appears AT&T has now pushed out an operating system update for the AT&T BlackBerry Bold 9000 smartphone according to the guys over at Crackberry.

Unfortunately the latest OS update from AT&T isn’t the BlackBerry 5.0 update most have been eagerly awaiting, however said OS update is a juicy official BlackBerry Bold 9000 update and is OS 4.6.0.304, although there’s no info on what changes or updates are included in this version.

As this is an official BlackBerry Bold 9000 update from AT&T, we can of course forego the usual disclaimer. So if you do happen to still be rocking an older operating system on your BlackBerry Bold 9000 smartphone you may just want to download and check out OS 4.6.0.304 which is available for download via the BlackBerry Software Download page.
