A:AnswerThey say on the 16th, but it's not guaranteed in any way. Last year Best Buy's "pre-orders" of Galaxy S8 were delayed by few days, the only excuse that they provided was that it was due to something out of their control. So... hit or miss.
A:AnswerStraight from the Bestbuy.com:
"*Savings are deducted off the full total price of the device and are reflected in reduced monthly payments over the life of the device. Savings offer does not apply to unlocked phones or Sprint Flex Lease. Savings valid online starting 12:01 a.m. ET on 3/2/18 or until release date of phone, whichever is earlier. "
A:AnswerNope. It doesn't apply to unlocked version.

A:AnswerBest Buy doesn't list it as having band 71, however another source with the same model number does list it as having band 71. I'm going to assume it does as Samsung only has one hardware set for all US phones, so I will be pre ordering the unlocked.
A:AnswerA Trade In should be available, the way I read the fine print is that the additional $100 will not be available, but I don't see any limitations on trade ins. Another question is how those trade ins are processed. So far I see the info that the trade in is given to you as a gift card that might not be used for the phone itself. That's what the BB rep says on their forum. I'm still trying to figure this one out myself.
