So with the big hype over Pokemon GO I personally have never been a big Pokemon fan. But I thought I would check it out and see what the hype was. But I quietly came to realize that Pokemon GO had Jailbreak detection inside the app. So a quick Google search later I came to a Reddit page on a user that has made a patch for Pokemon GO to remove the Jailbreak detection. 

I have tested this tweak and it looks to work fine. So for this you will need ifile and the Deb of his PokePatch or I believe you can add his repo in Cydia. It looks like he has not set up the auto install for Cydia repos so you will need to copy and paste it like the good old days. https://ryleyangus.com/repo hope this helps you enjoy Pokemon GO!
