Yeah, that's why I was confused. I want to try the developer preview, I'm just a little nervous that my phone will mess up or I'll have to hard reset or something. I don't want to deal with that, but I also don't want to wait for another month to get the official update. I've seen reviews online from people saying their 8xt works just fine, to others saying theirs kept rebooting. Also, sprint customers have been posting that their Samsung ativ is working smoothly with no problems at all. Maybe I'll keep researching until I make a final decision.
