Hi macrumors members, I was wondering if someone could answer this question for me or who has done it before. I have an iPhone 4 from Verizon that's still under contract until February 12, 2013. If I buy an iPhone 5 (full price) and then activate it on my account, am I able to sell my iPhone 4 to someone on ebay and have them still be able to activate the phone on their account? I'm not canceling my contract or making any changes to my plan. I'm just changing phones. Thanks in advance!
