Basically my sister upgraded to an iphone, but she didn't like it so she gave me the iphone. ATT took data plan off her line and put it on my line. Then during the weekend I dropped the iphone and the thing literally fell into piece because I was 3 stories up. Took it to apple store and they want me to pay $299 for a replacement and I just left. Since the only reason I'm staying with ATT is because of the iphone my sister gave me, so if I were to cancel my line will I be charge for early termination fee or force to pay anything? It's a family plan and the contract is up for all the lines except my sister's because she upgraded. Only her line is renew, but did my line also renew itself when I transferred the iphone?
