PokePatch

In case you are not able to play Pokémon Go on your iOS device because it is jailbroken, get the PokePatch jailbreak tweak. The game by default checks if a device is jailbroken so that it does not work on them. However, you can bypass this check using the PokePatch jailbreak tweak. You can download PokePatch from here.

PokemonGoAnywhere

Too lazy to go outside and catch Pokémons? Or cannot play the game due to some disability? Try the PokemonGoAnywhere jailbreak tweak. The simple tweak lets you walk anywhere in the game by simply tapping on the map. There is a slight problem though: you have to face the map north to go in any direction you want. Another risk of using this jailbreak tweak is that if caught, Niantic can ban your account from the game completely. There have not been any reports so far about users being banned for using this tweak, so you are safe for now.

Pokemon Lock

Only care about catching Pokémons? Don’t mind sacrificing the battery life of your iOS device and security for it? Try the Pokemon Lock jailbreak tweak then. The tweak will let you playPokémon right from the lock screen of your iPhone or iPad, which in turn will definitely annihilate its battery life. The tweak also requires you to disable passcode protection, but a little bit of security definitely cannot come in your way of catching Pokemons. Can it?
