If there are other hardware differences then they should have called them APP 3rd Gen; regardless, according to Apple chat the Lightning case APP2s get lossless as well.And you know that because you're a hardware technician/engineer in their R&D department? People always make **** like this up without knowing if there was a slight H2 chip revision - motherboard manufacturers do it all the time. Considering they also changed the IP rating, my guess is they aren't exactly the same revision as before.
