After all, if you should find yourself updating to any new piece of iOS software before it has been deemed safe to do so by a jailbreaking expert, you’re playing fast and loose with your right to a jailbroken device. And as we noted in an earlier article, in this day an age, updating is a one-way street, with downgrading looking to be an ever-distant memory.
