Sprint improves iPhone 8 preorder deal with strings attached

Sprint has announced that it’s upgrading its iPhone 8 preorder deal, with the carrier now offering an 18-month lease for free when you trade in an existing high-end device instead of the original 50 percent off lease it had originally offered. As is the case with all of Sprint’s leases, after the 18-month period expires, customers will then be able to return the phone and upgrade to a new device, or pay out six more months at the regular $29.17 / month price and own the phone.It&rsqu
