I've just bought a brand new iPad that's at version 7.1.2 out of the box. It seems that there's no current way to upgrade this to any version of iOS8 (I'm trying 8.1.2 but any version would do) except for the current one (8.3 now, that isn't jailbreakable). Am I stuck with what I have unless 8.3 gets broken, or unless I accept not having a jailbreak? I've tried downgrading iTunes, trying to get the iPad into pwned DFU mode but with no success. Any ideas?
