Verizon has still not added the GS3 to the Advanced Device List
I just got my account notated that the GS3 was not on 350-dollar ETF list when I activated my phone.
Who knows if they'll ever actually honor it, but in their terms they clearly state that advanced devices are the ones on the list. And it's not there.
They kinda flipped out and said it didn't matter, but worth a shot.
