Every iPhone comes with one year of hardware repair coverage through its limited warranty and up to 90 days of technical support. The AppleCare Protection Plan for iPhone extends your coverage to two years from the original purchase date of your iPhone. You get technical support and hardware repair coverage for your iPhone, battery, iPhone Bluetooth Headset, and included accessories.
The AppleCare Protection Plan can be purchased only while your iPhone is still covered under the standard one-year limited warranty. It costs $79.00.
