Couple of questions regarding an iPhone 4S I recently picked up off of eBay, running 6.1.3 First, I'd like to jailbreak it yet really can't find a jailbreak that works on this device on this firmware. I must be looking in the wrong spot (iClarified offers nothing). Second, my iPhone wants to update to iOS 8.1 and I don't want it to. Any way of preventing it? Thanks in advance!
