I'm a little late to the pre order party but I just pre ordered the ultra unlocked version directly from samsung. Not sure if I will put it on sprint or at&t but it feels good to have that option since I have multiple lines with both carriers. I also ordered the buds+ in black and a samsung leather case(I didn't see anything else I wanted). My go to case for all of my devices is the spigen tough armor hybrid case, just ordered one off of ebay.
