Over the past couple of days we’ve seen numerous unofficial BlackBerry OS updates, and today we finally have the release of an official update for the BlackBerry Curve 8520 reports Crackberry.

What a refreshing change to actually see an official update pushed out, and this time it’s from T-Mobile who has pushed out OS 4.6.1.305 for the BlackBerry Curve 8520 smartphone.

So if you didn’t bother to jump on the OS 5.0 bandwagon over the week you may just want to grab this official release and check it out by hoping over to the T-Mobile UK download site.
