iPhone Guru: iPhone 6s + 6s Plus: $199-$499, preorders start Sept. 12, in stores Sept. 25

After officially revealing the iPhone 6s and 6s Plus this morning, Apple confirmed pricing and availability details for both new models, with the following numbers assuming “on 24-month contract” or carrier-financed pricing. Off-contract pricing will be higher. Apple also announced an iPhone Upgrade Program, enabling customers to get the new iPhone each year with your choice of carrier – unlocked phone with AppleCare+, starting at $32 per month.

The iPhone 6s will be available for pre-order on September 12 in 16GB ($199), 64GB ($299), and 128GB ($399) capacities, each in space gray, silver, gold, or rose gold colors. Each iPhone 6s Plus model will sell for a $100 premium over the iPhone 6s, starting at 16GB ($299), 64GB ($399), and 128GB ($499). Apple will continue to offer the older iPhone 5s ($0), iPhone 6 ($99) and iPhone 6 Plus ($199) in 16GB capacities. The new iPhones will ship and become available in stores on September 25.

Today is notably the last day to lock in Gazelle’s guaranteed cash trade-in prices for older iPhones ahead of the iPhone 6s launch, as well as NextWorth’s special 9to5Mac reader bonus adding 10% to any iPhone trade-in (use promo code 9TO5MAC). Amazon is still offering aggressive trade-in values, assuming you want Amazon store credit rather than cash.
