I'm on the hunt for a nice Retina display Verizon 64GB iPad 3. They're hard to find, and when I do, they are often Jailbroken ios5.1.1 or something like that... is the jailbreaking the REASON that its still at ios5? Because ios5 is what it takes to jailbreak, and then they didn't update the system since? Can I always count on a jailbroken ios5 device (iphone or ipad) to be able to be put back to factory Apple ios5? I have no interest or knowlege about jailbroken devices, just a device that's still on ios5. Thanks in advance!
