Another year, another new iPhone. In fact this year, there are two new Apple flagships, the 4.7-inch iPhone 6 and the 5.5-inch iPhone 6 Plus. That adds just another layer of confusion to the many configuration options you're going to have to parse. So which iPhone should you buy when pre-orders open at midnight tonight?
Buy the 64GB 4.7-inch iPhone 6 on Verizon.
Why iPhone 6?
Unless you know for certain that you want a big, big phone, you're probably better off with the smaller version. For most people's sensibilities—and hands—4.7-inches of display real estate should be comfortable. While Plus has some clever software tricks worked in to make it more usable, it's still a little unwieldy.
The 16GB basic iPhone probably doesn't have enough storage space. As phones get faster and more powerful, we're carrying around more and more media and more resource-intensive apps than ever before. You'll bump up against 16GB faster than you think, at which point you're stuck, unless you get another phone.
To avoid frustrations like having to delete Infinity Blade III just so you can take a photo, get a higher capacity phone. Fortunately, Apple's new pricing scheme has made that a no-brainer. For just $100 more you get a 64GB model, whereas in previous years that kind of bump would cost twice as much.
If you don't have another contract you're married to for some reason, Verizon still offers the broadest LTE coverage across the country. It's not the cheapest contract you can buy, and speeds vary based on where you live, but for the most consistent coverage it's still your best bet.
Why an iPhone 6 Plus?
If you know you want a giant phone. Or you have giant hands and very baggy pants.
Why the cheaper 16GB model?
Only if you're really, really so broke that you're sure it's worth two years of inconvenience just to save $100.
If you're in an area where Verizon isn't great, or if you're inside T-Mobile's LTE coverage area and never leave (it's very fast, if you can get it). Or you're just cheap; whether you're a heavy data user or always stay under 2 GB, T-Mo is always going to be cheaper than AT&T and Verizon. And T-Mobile offers better incentives than the more affordable Sprint, like free international data, as well as being the first carrier to support Apple's new Wi-Fi Calling feature.
Sprint's coverage and speeds suffer compared to the competition, $60 unlimited talk, text, and data plan is a deal you can't beat.
Only if you're one of AT&T's remaining Unlimited hold outs and you staunchly refuse to give it up.
