anyone tried to get you older iphones traded in at At&t stores for the current promotion? I walked in to the AT&T store today and they have no idea about the promotion and they offer $19 for my scratch free working condition iphone 4 32gb. That is very insulting with such price and they have no knowledge of what AT&T's current promotion. The person said he tried to show the promotion print to the manager and the manager declined it because he point to a small crack on the phone...According to the promotion details, it said it needs to be a good functional condition and not a perfect new phone... Anyone has luck on this?
