So I've read that with Jelly Bean 4.2, they finally have implemented group messaging with the stock messaging app. Has anyone confirmed this with a Jelly Bean 4.2 rom on an AT&T GS3? I saw a screen shot where the option to turn group messaging on or off was in the properties of the messaging app. I have tried two different versions of the 4.2.2, and have not seen the option in the settings on either of them. I can't test it yet because I'm waiting for my nano sim adapter to arrive in the mail so I can use my nano sim from my iPhone 5. I want to go back to my GS3 full time, but I really need group texting to work, preferably with the stock messaging app.
