Update: The software release is 10.0.9.422, the actual OS version is 10.0.9.2743.
Verizon Wireless has officially launched the BlackBerry Z10 in stores today. Which means that as a new Z10 owner, the first thing you are going to want to do is update during the setup. The stock Verizon Z10 came with OS 10.0.9.2710 out of the box. During the setup you'll be prompted to update to OS 10.0.9.422. Make sure you update before you continue in your setup.
This must be an OS exclusive to Verizon as I haven't seen this version for any other carrier Z10's out there. Be sure to let us know about any findings/fixes in the comments below.
Note: The OS version for the Z10 can be found by typing "myver" on your Z10 keyboard.
