I just checked my store in Culver City, Los Angeles, CA. No Captivate. Guy checked in the back, then said that they don't have it and even if they did, they can't sell it until Sunday. He also couldn't tell me the off-contract price because he said that he has not received a press release for the phone yet.
I am going to buy an iphone 4, on contract, sell it for $800, and use the cash to buy a captivate, and have $450 leftover.
This is all assuming the off-contract price really is $350, which still sounds too good to be true. Anyone else have this same plan?
