Here are the new iOS 5.1.1 (9B206) links. Rumor has it there’s an untethered jailbreak for 5.1.1 around, but it’s not public yet, so hold off if that’s your thing. It’s been discovered that the new iPad2,4 is a 32nm refresh of the A5 chip. The die-shrink is mainly to benefit Apple, but if you happen to get one of these new ones, it should run a little cooler and have better battery life due to the new process.
