It sucks that they won't let you pre order if you're wanting to get two iPhones on a family plan. I was all ready to pre order last night and set up my AT&T account (I'll be a new customer).
I guess I'll just have to wait until launch day.
Edit: Wait, I just checked on AT&T's website again and it says "limit one per household when ordering online." Maybe if I go into the AT&T store and pre order, I can get two iPhones. I must call now and find out!
Edit 2: I just called my local AT&T store and they said there is a limit of one iPhone per household when pre ordering. It doesn't matter if you walk into a store, order it over the phone, or order it online, the limit of one still applies. I guess I'll be one of the unlucky people without a pre order.
