My friend purchased an iPhone 5 (US, CDMA model) from eBay but we are in New Zealand. First step is that I need to jailbreak it. It's currently got iOS 6.1.4 installed and from what I can gather it needs to be on 6.1.2 or earlier to be jailbroken. Is that right? It was on 6.1.4 when he got it, is it possible to downgrade somehow?
