Re: need help with iphone
Found this info:
There are two iPhone 7 models: model #A1660 (Sprint, Verizon) and model #A1778 (T-Mobile, AT&T). There are also two iPhone 7 Plus models: model #A1661 (Sprint, Verizon) and model #A1784 (T-Mobile, AT&T). Each model number supports different technology and will only work with select carrier networks.
