Latest research data shows that iPhone 7 was the most-selling smartphone in the world in the first half of 2017. The bad news for Apple is that the handset is still more popular than the recently launched iPhone 8 and iPhone 8 Plus and a recent price cut doesn't help the popularity of new models.

Because of that, Apple has decided to discontinue the top model - iPhone 7 256 GB. Apple's online store shows that the Apple iPhone 7 and Apple iPhone 7 Plus are both now available only in 32 GB and 128 GB versions. It will be interesting to see when other iPhone 7 models will be discontinued.
