If your unit is on the list then Apple will fix it free of charge (within two years of the original purchase date) by sending it to a repair center. If you've already paid for a repair then look out for an email about reimbursement, and if it doesn't show up then give Apple a call. This is hardly the first recall/repair program we've seen for various iPhone issues, which have recently included battery problems (that preceded the software update that slowed down affected phones) for the iPhone 6s and iPhone 6 Plus "touch disease."
