The (silver) BlackBerry Keyone model unlocked & compatible with the Verizon network has been sold for 3 months now, but only directly from Best Buy & Amazon.

The availability has been somewhat sporadic due to sales and issues with the screen hardware separating from the device and software fixes. As of today Amazon shows the Verizon compatible version as out of stock but it is available at Best Buy's for order and shipping again.

The KeyOne isn't made by BlackBerry, as BlackBerry doesn't manufacture devices or hardware since their company restructuring. BlackBerry does make software offer design licensing for products.

The KeyOne is an Android device made by TCL, a Chinese electronics company. They licensed the BlackBerry keyboard design for the phone which is why the model carries the name. Definitely helpful for brand recognition.

'BlackBerry' devices released since the end of 2015 have been running the Android operating system as the BlackBerry OS like on your Z30 had been retired.
