I'm looking to buy an out of contract iPhone 6 Plus to use with Verizon. My local Apple store has been out of all 6+'s but according to apple's website they have a Sprint one available now in stock. Does anyone know if I can go in and buy that one out of contract ($850 for 64GB plus) and use it with verizon? Or is it already going to be tied to sprint? I've read that the Verizon iPhone 6's can be used with all carriers. Are they all "unlocked" until you renew and activate it with a certain provider? Thanks!
