Just wanted some feedback. I just purchased an iPhone 7 jet black Verizon at the Apple Store today and am using it on the T-Mobile network because the Verizon iPhones are factory unlocked. They didn't have any T-Mobile iPhone 7 available. I contacted T-Mobile tech support and they said because of the CDMA (Verizon iphone) being on the GSM (T-Mobile network), my Verizon iphone 7 won't be fully utilized on the T-mobile network with their extra LTE. I am debating if I should exchange my Verizon for a T-Mobile version, depending on if using a t-mobile iphone on the t-mobile network makes that much of a difference? I am aware that the verizon iphone will work on all the carriers and the tmobile won't work on verizon or sprint carriers. But do you think its worth exchanging the verizon iphone 7 for a tmobile iphone 7?
