I would prefer to just buy an iPhone 8 Plus outright and have the freedom of choosing my service. On Apple's website, the shipping estimates for an unlocked 8 plus is 2-3 weeks, and there doesn't appear to be any in stock in the Apple Stores. Yet, if you choose a service provider with the phone, it ships in 1-3 days and they're available in the store. What is so different about an unlocked phone that their supply is constrained? I was hoping to be able to buy an unlocked iPhone 8 Plus in a store this week, but according to the website that's not going to happen evidently.
