If your iPhone is Jailbroken you can install pokemon go pretty easily.
Download iTunes and iFunbox to your computer.
PS: I prefer iFunbox Classic. :)
Download the IPA.
Open iFunbox and;
- Select your iPhone
- Locate the IPA
Pokemon Go has a jailbreak check at the splash screen, in order to remove that;
- Open Cydia
- Add the repo
https://ryleyangus.com/repo(If you don't already have it)
- Search for
PokePatchand install it
Now you're ready to start playing Pokemon Go.
PS: Don't forget the Pikachu easter egg. :)
