So I've had my iPad 2 64gig Wi-Fi for about 4 months, and loving it. Got it jailbroken and works like a charm. The thing is that my son's birthday is coming soon and I'm thinking about getting him an iPad 2. So I'm wondering if Apple update new shipments with the latest updates of iOS 4, or do they ship with a certain firmware as standard? In other words, are the latest batches of iPad 2's still jb-able? Thanks in advance. Much appreciated.
