My iphone has never been jailbroken though there might be advantages. However, I would always install a custom rom onto my phone when I used android. Cyanogen mod notisably out performs any stock android I've used, it hasn't got any of the bloat, has more os setting and customisations, being rooted it means I can use ad blocking software, it is more up to date and in many cases has proven stabler and runs apps better than stock... and normaly has better battry life.

Of course not all stock androids are equal, but it's amasing how much better cyanogen mod is to the vast amount of stock versons even when you ignore the perks of it being rooted.

Thennnnnnn whats the problem?

So gyms were a critical part of the game for you then, I assume? Because that's the only place right now where cheaters can affect you unless I'm forgetting something.

As much as I hate cheaters in games, blocking rooted/jailbroken devices is fucking annoying. Last time I touched an Apple device, it was a 2nd Gen iPod Touch. I really hated that UI and how constrictive it was. Took some guts jailbreaking it then I got myself a pretty decent looking UI. Moves like these is one lazy attempt at stopping cheating.

As an android user, they ask me what is to be gained. Basically customization is what I like. On my old Note 3 it's hard to customize the system UI without rooting. Not to mention removing or stopping pesky unnecssary bloatwares. Good thing I don't play this game otherwise this will piss me off to no end.

Gyms are an essential part of the game. It gives you more stuff to do, like leveling up your pokemons or trying to capture pokemons with strong IV to conquer gyms and winning these places is the only way you can earn in game money without using your credit card.

I wouldn't exactly call them 'essential'. They take a lot of time to capture, the battle system is really boring, and in general they're not very important. If you have the Pokémon to do it efficiently then sure, they're good, but if not, at least I have better use for my time than battling over gyms. And it's not like you even need coins for much. I was happy enough to spend a few euros to get some more inventory space, and I haven't needed coins for anything else. Coins are useful, sure, but you can do just fine even without.

There are so many things to fix in this game and what are Niantic doing? They are wasting their time with something unneccassry like this... :(

I root my android for the same reason, but I use the Eclipse mod as opposed to Cyanogen.  Guess I am now ineligible to play.  This makes twice the game has blocked my access.  Time to move on I guess.

Huh... it doesn't work on Rooted phones? Guess I can't play it... not that I particularly want to though, far too social for me.

Pokémon was too good for mobile, they had to lower its quality somehow.
