So I have not jailbreaked a device since ios 6 on my iphone 3GS. Now I want to do it on my ipad mini that is actually still on ios 6. I want it to be on 8.4 with cydia. But I read alot of problems on this. So a simple question is it possible to update my ipad to ios 8.4 and jailbreak it with a tool that also adds cydia to it? And will I still be abble to use apps like appcacke??? Also I read that you need a specific version of itunes??? Thanks in advance for the info.
