So I already have a contract with AT&T, however I think the two year deal runs out this christmas. I was just wondering what would exactly be the process I would go through if I bought an iPhone July 11th. From my understanding, I have to get a brand new contract for like $59.99 or extend my current one for like $20.00 and they would both give me unlimited texting, voicemail, and web. Also, I saw on the Apple website that the activation process would require a credit card, which I don't have, I only use debit. Lastly, wouldn't it make since that all I have to do is put in the sim card from my current phone into my iPhone, and it would just work since I'm already on AT&T. Any information answering these questions would be greatly appreciated.
