Every iPhone, iPad, iPod, and Mac comes with a one year warranty against manufacturing defects and hardware failures. If you choose, you can also extend that warranty for additional years with AppleCare. Regardless which warranty you have, you can easily find out whether or not your Apple products are currently covered. Here's how:
How to check your AppleCare coverage on an iPhone, iPad, iPod, or Mac
Type in the serial number or IMEI of your Apple product that you found in step 1.
You should now see a page letting you know whether or not you're in warranty.
If you haven't extended your product coverage with AppleCare, you can purchase a plan online by clicking on the button to extend your coverage under the AppleCare coverage section. If you're within warranty you can also set up a repair using this page or contact AppleCare support.
For those of you with multiple Apple products, do you always buy AppleCare plans? I find myself always buying it for Macs since I keep those a lot longer but not for iPads and iPhones since I upgrade those every year. What about you? Let me know in the comments!
