Customers can initiate pull request today, general rollout begins in batches from February 11
Sprint has given word that customers with an HTC One can now pull down the Android 4.4 KitKat and HTC Sense 5.5 update directly to their phones starting today. Nothing official for a change log was given, but it should be the same exact KitKat and Sense 5.5 update that has been on the unlocked and European phones for a bit, and that Canada just started getting this morning.
HTC already gave us a heads-up that they could miss their self-imposed 90-day turn around time to get KitKat out to customers with a One, but it looks like Sprint isn't making that one true for their customers.
If you're the impatient type — and you know you are — fire up your settings and check for your KitKat update. Hopper in the comments when you get it, and be sure to hit the forums to share your thoughts and experiences.
