Customers can initiate pull request
Updated update: Things are good. Go download your update. Someone forgot to factor the time Google needs to get the file itself on the servers, and things backed up 12 hours.
Update: Looks like someone jumped the gun, as the Sprint admin who posted about the update has walked things back a bit, adding that "this software update is on hold and should be pushed to production very soon. Apologize for the inconvenience." More likely is that it just wasn't meant to be made public yet. Either way, hang tight. We should see this soon.
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. Hop in the comments when you get it, and be sure to hit the forums to share your thoughts and experiences.
