Oh okay. Much clearer to me now. With that said shouldn't the unlocked phones being made presently be equipped with the same internals as Tmobiles IPhone, because in a nutshell it seems getting the Tmobile iphone would be better. Question though, would it work in reverse, lets say I didnt like Tmobile and wanted to go to Att would my Tmobile Iphone work perfectly?
Some of the Apple stores still have the old unlocked model in stock. When I went to buy mine I asked for the T-Mobile one but the guy said why not just get the unlocked one since they're the same. Took it home and saw a lot of Edge and looked at the back of the box and noticed it was the old unlocked model. Took it back the next day and exchanged for the T-Mobile model.
It works in reverse. The current T-Mobile model supports all the bands that are needed to run 4G and LTE on AT&T. Once the current crop of AT&T iPhones run out, the ones sold at AT&T will also be the new one that supports T-Mobile's AWS bands.
