If you have the AT&T locked version of the Blackberry Priv, you should start seeing the March security update coming to your device starting today. The update comes 2 weeks-and-a-day after it was released by Google themselves so all-in-all, that is not a bad time frame for a carrier locked device. Further, the update makes AT&T the first carrier here in the US to get the update to the Priv on their network with T-Mobile, Verizon and Sprint all having the device but none of them have pushed out this update. For a point of reference, the update came out the same week as Google released it on the unlocked version of the Priv.
As you have undoubtedly read by now, the March security update is the monthly Android update issued by Google to address security issues and other fixes. There are no new features in this update but users are encourage to download and install it once it hits their Priv. AT&T is pushing the update out but you can always manually check for it by going to Settings>About Phone>Software Update. That doesn’t necessarily mean it will push down to you immediately but it never hurts to try.

Kudos to AT&T for getting this update out in a timely manner!
