Apple launched the iPod line of portable media players in October 2001 and marked a change in the evolution of digital music. Since its launch of the first iPod, Apple has introduced different versions of the iPod (Touch, Classic, Nano, Shuffle) with multiple generations for each of them.The latest generation of the iPod Touch offers a multi-touch graphical user interface and comes with the state of the art Retina display, HD video recording, Face Time capabilities and built in Nike + iPod support. The iPod Touch has almost all the features of an iPhone except access to cellular networks and GPS navigation. iPods only officially support apps from Apple or web-based apps. Some iPods are modified by users to be "jailbroken" so that they can have unofficial and unsupported apps installed on them. Not all jailbroken or unlocked iPods are the same so it is important for shoppers to understand the exact nature of the jailbreak or unlock from the seller.The iPod Classic 7th generation with its hard drive and 160 GB of storage space makes it the dream device for user who would like to have all their music, movies, TV shows, audio books and photos all the time, everywhere! It can hold up to 40,000 songs, 200 hours of video or 25,000 photos*. Ideal for a fitness oriented lifestyle, the compact iPod Nano uses flash memory for storage and the latest generation comes with a built in FM radio, pedometer and multi-touch display. Nike + iPod support can be purchased separately. The 1st generation of the iPod Nano was introduced as a replacement for the iPod mini which has been discontinued by Apple. The smallest and lightest iPod is the iPod Shuffle. Songs can be navigated with buttons and voice over to tell you the song or playlist eliminating the need for a screen. Its small size makes it wearable and, as the name suggests, it is designed to easily load songs and play them in a random order.All iPods work with iTunes to purchase, rip, transfer and load songs and other content when connected to your computer. All iPods come with rechargeable lithium-based batteries. Like other rechargeable batteries, these batteries may eventually require replacement. The one year warranty with iPods includes replacements coverage for a defective battery. Warranty coverage can be extended to two years from the date of purchase with the AppleCare Protection Plan for iPod. During this period Apple will replace the battery if it drops to below 50% of its original capacity. For out of warranty iPods, users can get a replacement using Apple's battery replacement program. An easy way to personalize iPods is by adding a laser-engraved message to it. If your iPod is under warranty and needs to be replaced, Apple will engrave the new iPod with the same message as long as the original engraving was done through Apple.
