I was able to purchase a new, sealed iPhone SE at a great discount on eBay. It has not shipped or arrived yet, however I do have serial number, model number, and IMEI number from photos. I messaged the seller asking if this is a factory unlocked model from Apple or if it was from a particular carrier and unlocked later on. He did not know. Knowing that the phone is now unlocked, would it matter if it was originally an iPhone from another carrier if I intend to use it on Verizon? I believe I've heard that models from other carriers may not have all of the hardware / software to operate at 100% capacity on the Verizon network. I apologize if this is an obvious question.
