Hello - I have a few questions I'm hoping someone could help me with. I'd like to order the new Iphone 7 Plus in black. I've searched msgs on the availability and shipping issues, people had been saying shipping should start mid Nov. So - my question is - have they started shipping yet? I'm not sure whether I should order now to get in the 'que' or if that even matters if they're still not in ? If I order now and the phones don't ship for months - am I charged now? Also - am I able to switch my current phone number to the new phone? Can I keep the same plan I have now ? I see there are a few discounts when I buy with a 'tab' - do these same discounts apply if I purchase outright or do I have to do this with the tab? Appreciate anyone's help with these questions.
