I'm getting a tmo version to use on att, I mean how do I test if it supports band 30? I have an in store reservation for the upgrade program also, I'm thinking of getting an att version instead since it has CDMA compatibility.
They both have CDMA compatibility.
Model A1633 and A 1634 have band 30
Model A1688 and A 1687 do not
Everything else is the same.
