It's awesome!
It's true. I'm officially updated to Jelly Bean on my AT&T Galaxy S3!
This is exactly why I dropped my Motorola Droid Bionic and Verizon's Big Red Network for AT&T. Verizon and Motorola fuck all their customers for updates. I mean come on Key Lime Pie is just around the corner and this phone is barely getting ICS and probably will NEVER officially get Jelly Bean. That is absolute CRAP how long Verizon takes for everything.

This is extremely upsetting in my opinion. I love my US Galaxy SIII with the S4 Snapdragon, but I definitely would have loved it much more with the Quad-Core Exynos processor and still with LTE and 2GB of ram.
