Hi folks-- I purchase my iPhone full price without contract to keep Verizon Unlimited Data. I am out of contract. Can I go to Apple Retail, purchase the phone in-person on launch day at full price, and then cancel my Verizon preorder? Will Apple Retail even offer full price purchases on launch day? (Apple.com only permits 2-year promotional upgrades for those out of contract.) I'm wondering if the equipment order in the Verizon queue will restrict my Apple Retail in-store launch day purchase. Thanks!
