My iPhone was replaced on April 5th. The Genius said that they could replace it, but I would need to activate; as I hadn't before April. When I got home with my new iPhone I activated, registered the product, and check my warranty status. When I checked the status for both (new and old) iPhones, they both gave me the error "Our records indicate that this product has been replaced. Please provide your product's replacement serial number to find its support and warranty coverage information. For more information, please contact us." The 'genius' had me sign a work confirmation, but they gave me no receipt for the replacement. Is there any way to get this problem fixed?
