BlackBerry is now pushing out its first Marshmallow beta update for the Priv to those who signed up to help test it.

T-Mobile customers who signed up for the beta will begin receiving their invites to download the update in 24 hours, according to Nathan Webster who is the manager of BlackBerry's beta program.

So, if you are on the current beta be sure to check for an update. If you are a T-Mobile customer, keep an eye on your inbox in the coming days for your invite. The update weighs in at over 1.7GB, so you will want to make sure you have plenty of battery power and a good Wi-Fi connection to get it downloaded.
