For the past 6 months or so I've been running iOS jailbroken at 5.1.1 on both my iPhone and iPad. Now I've noticed that it's possible to jailbreak up to 6.12 but this leaves me with a few queries: Is there a way to update officially to 6.12 and then jailbreak rather than update all the way to 6.13? I have an iPad 2 and an iPhone 4. Will these devices (particularly the iPhone 4) struggle performance-wise with iOS 6x? I know it'll be usable but I find it starting to chug a bit even now on 5.1.1.... Do people think it's actually worth me updating to 6.12 or will I end up losing some good features? (like Google Maps for instance....) I'd be grateful to hear some opinions!
