Samsung Galaxy S III for T-Mobile USA receives its Jelly Bean update

Sprint was the first major US carrier to start delivering Jelly Bean to Galaxy S III owners, but it no longer stands alone now that the T-Mobile edition is officially receiving its update. If you're part of the initial crop deemed eligible on Magenta's network, a check either over-the-air or through Kies should put Android 4.1.1 on the Samsung flagship. T-Mobile's version of the upgrade delivers the expected dashes of Google Now and Project Butter as well provider-specific fixes for WiFi calling. Don't worry if there isn't an immediate notice, as carrier-linked OS updates usually take weeks to get everyone on the same page; the main question is when all the other big US networks will follow suit.
