This whole time I was planning on doing a cross upgrade. I saw where my dad's account had 2 lines saying "congrats-you are eligible for early iphone upgrade". So I figured that both lines were eligible to get an iphone. I called customer service to find out that means you have to pay $250 over the price of the iphone compared to if it was eligible for a full upgrade. I did not know that. The good news is one of those lines is eligible for an upgrade November 4th. Since it's so close, AT&T customer service said most actual AT&T retail stores would let me get a full upgrade right now. She said Best Buy or Target would not be able to before November 4th. Is this true? She said they use different systems. I figure BB or Target could just call AT&T, and AT&T would approve it It's only about 10 days away.
