I got looking into it, and it looks like the Optimux 3D is going to Tmobile, from what I have found, so that puts it out of the question.
Galaxy S II is up in the air for AT&T or Verizon.
Got excited when I saw it for mid-late march, but then saw it got delayed to May??
I prefer the Galaxy S II over the TB, but without knowing if it will hit Verizon or not, and not knowing when, kinda buts a damper on things as well.
So, looks like I am probably just going to stick with Thunderbolt.
This will be my first android smartphone, so really excited.
If some news comes out on the Galaxy S II before the TB release, I would for sure consider waiting until May, though its going to drive me crazy.
