Sorry for my naivety, but I've never pre-ordered online for an iPhone before. Just looking for some advice. When I pre-order tonight, is the Apple Store app the best place to go? If not, where? Upon ordering online, will I have the option for different payment plans (in full, Apple Upgrade, ATT Next, etc.)? Speaking of payment plans, which would be the best deal without changing my current ATT plan? Any help would be great as I've never done this before: my current iPhone 5 is from 2012 and I walked into the store and bought it.
