I'm planning to buy the iphone from the At&t website, so I'll go through with the ordering process, and I'll put my info in and they process my order. First, will they send me the phone? Second, if they tell me I cant get the service because my credit score is too low will they automatically charge me the deposit value. Third, what do I do when I get the phone and can't activate it? Will their be any use for it?
