Guys. With iUP we get unlocked phones so we are not tied down to a carrier. But with the iPhone 7 launch, there are 2 variants of the Modems Model A1660/A1661 with Qualcomm Snapdragon X12 Modem for Sprint and Verizon but also works on AT&T and T-Mobile Model A1778/A1784 with Intel XMM 7360 Modem for AT&T and T-Mobile and will not work on Sprint nor Verizon Currently I am on At&T but planning to switch to Verizon. And I got the A1784 model with iUP. My phone would be useless on Verizon network now. Anyone know more about this that I am missing?
