You are correct I am on the U firmware. I'll take your recommendation and wait.You are on carrier U firmware. This is for U1 unlocked. Looks like you on stock current firmware. You would have to flash over and wipe your device to the beginning of the beta path, then update 4 individual times to get to it. Better off waiting for it to drop OTA for you when official is released. Probably only gonna be a couple of weeks anyway.
Thanks!
