I just visited my local ATT store. It's not a corporate store. The store manager said that if I preordered (i.e. paying in full right now) I would be guaranteed the 6+ 128gb model I want. However, he said that I would have to buy a new "secure" SIM card for $20 and pay $30 "shipping and handling". This adds on $50 to the cost of the phone. I am dubious about these additional charges. He claims the store pays $60 shipping for each phone, so we're actually splitting the fee. I also have not read anything about a "secure" SIM card. I am not an idiot, but if it means I am ensured a 6+ without having to wait in line, then it's still worth it for me. Has anyone experienced something similar?
