I want to purchase an iPhone at full price with no contract but at the summary, I'm seeing a two year commitment with a 1 time upgrade free. Not sure what I'm missing if I'm paying for the phone outright? I assumed if you paid for the phone in full, you wouldn't be bound to renew to a new two years? I understand I'm still in my contract for my iPhone 5s which is fine, but I'm buying a phone at full price, why would I have to re-sign a new 2 year agreement? Can't I just fulfill my current two year agreement whilst buying another phone outright? Sorry, new to all this but this seems crazy.
