I'm not getting any bites on my black ATT 64gb 5 on Craigslist at $520. I have an offer from Nextworth for $451 but it expires soon. Anyone know if last model prices generally go up again a while after launch? If so I'll wait it out; I'm not desperate for the money. But if I'll never be able to get more than $450 on Craigslist is rather just skip the hassle and mail it to next worth. Also, anyone know if you need to include the lightning cable with the next worth phone? Doesn't say anything about it... Thanks!
