as title suggests, when do we think we will see the iphone 6 come down in price, new and 2nd hand? will apple keep it the same price until the new phone is released?
Apple doesn't really discount devices but the carriers will.
Given I've just received an email from Verizon offering $200 off for the iPhone 6/6 Plus if I upgrade (with either 2-year or EDGE), I'm thinking they're starting already.
They do the 8GB downgrade for the "free" iPhone. For the next tier up, I believe Apple now offers 2 storage models. In general though, I've found carrier discounts just prior to the new iPhone's release to be much better.
