Owners of the HTC One on AT&T have been patiently waiting for their update to KitKat since Friday's announcement that it had passed technical approval. According to AT&T's blog, the OTA just started rolling out to big blue customers earlier today. In addition to all of the Android 4.4 goodness, this update boasts improvements to the user interface, phone app, caller ID, BlinkFeed, and the long awaited update to Sense 5.5.

You will definitely want to be connected to Wi-Fi, this update comes in at 620 MB. As usual, your One should be charged up to at least 50% battery. Go to Settings -> About Phone -> System Updates -> Download, then let it do its thing. The update probably isn't going out to everybody simultaneously, so you might have to wait just a bit for your turn. Happy upgrading!!!
