Niantic has just announced that Pokémon Go will soon stop supporting Apple devices that are not capable of upgrading to iOS 11. In other words, you won't be able to play the game in Older iPhone models, like the the iPhone 5, iPhone 5C.
This change will take effect on February 28, 2018. After the update, those with phones not running iOS 11 or higher will no longer have access to their account. You'll need to upgrade or use another phone to continue playing for those precious Pokécoins. “This change is a result of improvements to Pokémon Go that push the application beyond the capabilities of the operating systems on such devices.” says Niantic.
Pokémon Go is a different game if you were the first batch of players hell bent on catching all of the first generation of Pokémon. The second and third generation of Pokémon are now in the wild and they now have a Raid System that encourages cooperation with other players to defeat these strong Pokémon making camp at Pokéstops for a limited time. It also has a new weather system and the latest update added new improvements to its augmented reality features.
Pokémon Go was released in July of 2016 and found sudden fame since it's release worldwide. A sudden drop of players soon followed but found a steady community playing daily and the many updates Niantic has released have kept it as one of the more popular titles in mobile.
