Hello, I bought the 10.5 Ipad pro last month and to my surprise, it came with 11.3.1. My original intention was never to JB the ipad pro but since it is jb'able, I did it and it works wonder. My main purpose of JB is to block ads. I heard the IOS 12 is a lot better and stable than 11. Is it silly to give up JB and go 12? Your feedback is much appreciated. Thanks!
