Pokemon Go is available on iOS and Android. When will this option come up it's still a mystery, as there is no word about it in the beta.
We would imagine that following Groudon's exit, Niantic will release Kyogre, followed by fellow legendary Rayquaza a month later in February.
In addition to the above, it's also worth noting that the game just relased another batch of Ex-Raid passes. There's so many more players that have since given up on the EX Raids. Though fans with the game probably have higher iPhone models, the few that do have outdated models are going to be disappointed with this announcement. Any of you that do, though, you're out of luck, I guess. Way to kill my motivation on this game.
Which sort of highlights the problem with the whole Ex-Raid system, as there appears to be no reasoning behind who gets sent an invite. The update brought a new AR+ encounter mode for Trainers on iPhone 6s and newer iPhones running iOS 11, as well as "improved Pokemon Go responsiveness".
