I picked up the T-Mobile version Saturday. no screen protector pre-installed. They only sell the 256storage/8ram version. They do have both Blue and Gray color options.
From a software standpoint there wasn't much pre-installed, the normal T-Mobile bundled apps and that's really it.
T-Mobile version also doesn't have the FNatic Mode. It does have the Game Mode
It sounds like from what I've read the FNatic Mode takes advantage of the dual SIM card so this could be why it was removed, I'm not really sure what else the mode has that would make them remove the feature.
Anyways ending my 2nd day with the phone and it's a really nice experience so far. I'm coming from an Galaxy S8 Active.
