Update 2: Never mind AT&T's blog post ... the update most definitely is available now. It's a whopping 630 MB.

Update: And AT&T has pulled its blog post announcing all this. Figures.

Original: AT&T today finally announced that its HTC One X is getting Android 4.1 Jelly Bean starting today. 

We'll let that sink in for a minute. This one's been a long time coming.

In addition to the expected Google improvements, such as Google Now, Project Butter, better notifications and all those other improvements we've been enjoying on other phones for some time, you'll get:

  • A new countdown timer for the front-facing camera. 
  • ISIS mobile payments. This is worthless unless you're in Austin, Texas, or Salt Lake City.
  • AT&T Locker, so you can store your photos, videos and docs in the cloud. Which you can also do just fine without AT&T-specific software.
  • AT&T DriveMode, which can be set up to send custom replies to incoming messages once your phone (presumably in a car) is going more than 25 mph. This is a good thing. Use it.
  • AT&T Messages: A single inbox for texts, calls and voicemails, accessible from your phone, tablet or computer. Should interesting.

AT&T says the update should be available any time now, though we don't see it yet, and now we've got that blasted "You can't check for updates again for another 24 hours," which is as annoying as ever.
