I searched and found some old posts with people asking the same question without answers so I thought I would share my experience. My earphones for my iPhone 3GS stopped working and I called Apple for a replacement with the intention of paying. They still replace them for free like they have in the past for iPods. They took down my credit card information just in case I don't send my broken pair back to them, but I am very happy to get a free replacement! They also ship them priority overnight through FedEx for free. Thank you Apple!
