Verizon finally took some time off promoting the droid dna to approve the gs3 JB update
Verizon Approves Jelly Bean Update for Galaxy S3
The update includes all of the Jelly Bean features youd expect, like Google Now (even though they label it above as Plus), better notifications, smarter widgets, and Project Butter. Beyond Jelly Bean, Verizon also included support for Isis Mobile Wallet (still only available in test markets), turned the phone into a global roaming beast, and fixed a variety of bugs.
The update appears to be 62MB in size. The build number is VRBLK3, which leaked last week.
