Which would you choose? What if the Mini 2 64GB was Black/Space Grey? What if the Mini 4 64GB was White/Gold? Mini 2 64GB $100 (used) and Mini 4 64GB $499 (new)? For price sake, better to stick with Mini 2? How is it with iOS 9.1? And if we can't discuss jailbreaks, let me know, but how does Medusa run on the Mini 2 which allows a variation of multitasking that the Mini 4 officially has? Thanks!
