The iPhone is covered by a one-year limited warranty that covers it against defect, but not misuse. So, for example, if you bounce it off the wall or throw it on the ground, you’re responsible for the damages. In addition, if you hack the device, open up the case, or make unauthorized repairs, you void the warranty. You can extend the iPhone limited warranty for an additional year for $69 ($59 for the iPod touch). Repair for an iPhone not covered by a warranty will cost you $200-$250 plus shipping ($150-$250 plus shipping for the iPod touch). Replacing the battery costs $69 plus shipping ($79 plus shipping for the iPod touch). You can purchase this extension and access information about the repair service at the iPhone’s support Web page (apple.com/ support/iphone).
