While everyone was busy admiring and criticizing the new Apple iPhone 7 and 7 Plus, Barely someone have noticed that Apple has removed iPhone 5S, iPhone 6, iPhone 6 Plus from their website. They might have removed them because they are discontinuing the device from this year. However, the older phones should still be available with third party retailers until their stocks last.
Apple has also removed their older models of iPhones previously for discontinuing them. The last years iPhone 6s and 6s Plus are only available in 32GB storage and 128GB storage variants. The smaller iPhone SE is still listed, and is available in 16GB and 64GB variants.
