So the thing is, the S5 is a pretty good deal when you go Swappa (not an option here, I guess) or with one of those crazy clearance type things instead of buying from the carrier (and you still haven't explained what the carrier is, because that does matter).For the guy in this thread that said why not pay more for the S6? Why the hell would I pay more money for something that is even MORE of an overkill phone than the S5 already is.
There is no crazy S5 discount now, but there *is* one for the S6, new for $470:

This is for the G920i, which has all the US GSM bands including T-Mo's band 12.
