Even though the Kit Kat (Android 4.4) update for the HTC One reached the “certification” stage a couple of weeks back, followed by a confirmation last week from HTC USA president Jason Mackenzie that the update was still about a week out, HTC went ahead and surprised us on Saturday morning with an announcement that the Sprint variant was receiving a build already. The other carrier variants are more than likely still a week or two away, but Sprint was able to give approval somewhat early.
If you own the Sprint One, you can pull the update by heading into Settings-> About -> Software updates. If you miss this message, your phone will receive the update by over-the-air push on February 11.
Any bets on which variant is next?
