I'm looking at the bottom of the iPhone 6 page at the Apple Store site. I see the following models listed: Model A1549 (GSM) - I'm guessing these two are AT&T Model A1522 (GSM) Model A1549 (CDMA) - I'm guessing these two are for Verizon Model A1522 (CDMA) Model A1586 - What are these for? Model A1524 My questions are: 1) What carrier(s) are Model A1586/A1524 for? 2) What model is the T-mobile contract-free phone using? The reason I'm curious is because the A1586/A1524 model seems to have the bands of the A1549 GSM & CDMA models combined, plus a few more, which seems to make it a more useful/universal phone to buy. Just wondering how to get it.
