I Want to install pokemon go but it tells me that i need to update to ios 8.0, i currently have the ios 7.0.2
iPhone 4 can only upgrade to iOS 7.1.2, so you'll need an iPhone 4s or higher to be able to download Pokémon.
There isn´t possibility to play Pokemon Go on your iPhone. One thing is that iPhone 4 can´t run higher iOS than 7, but second thing is, that even on iPhone 4S the game will be very slow. If you want to experience great gaming, you must play game at minimum of iPhone 5, 5s, etc. For best experience and low cost try iPhone SE.
