Q: Why different models of iPhone 7?

If A1660 and A1661 cover both CDMA and GSM bands, why do 1778 and 1784 exist? What If I buy a 1660 and use it on Tmobile or ATT? Will any of my speeds be gimped compared to a 1784? I've heard that happens. If I want the best speeds possible do I NEED to get a 1784 if I go to Tmobile or ATT?


I'd like to get an unlocked phone for use on tmobile, att or cricket but not sure which to get
