Sprint has began pushing out an update to the HTC One Max that brings it up to version 3.02.651.5. This update adds Wi-Fi Calling and Sense 6. It is a staged roll out, as always, so head to your settings, and start angrily mashing away on the update button. You could also be civilized and wait, though. Didn’t think so; here is how to check: navigate to Settings > System Updates > HTC Software Update > Check now > hope and pray it shows up as available.
