Hi, i am still under my contract which terminates next year with verizon. If i were to preorder the iphone 5 when it is available to do so, i purchase it unlocked or at full retail price essentially.. So, what happens next? Do i have to call verizon to end my contract with my iphone 4 or can i just plug the iphone 5 into itunes --> automatically transfer # and service to iphone 5 and auto cancel iphone 4 contract ? and since my contract with iphone 4 will be terminated would i have to pay the ETF as i have alrdy payed for the iphone 5 at full retail? thanks.
