Everything you see and do on iPhone 4S looks amazing. That's because the Retina display's pixel density is so high, your eye is unable to distinguish individual pixels.
Advanced optics, a custom lens and an 8-megapixel sensor let you capture high-quality photos. And you can shoot beautiful movies in full 1080p HD.
Every iPhone includes 90 days of free telephone technical support and a one-year limited warranty.
The unlocked iPhone includes all the features of iPhone but without a contract commitment. You can activate and use it on the supported GSM wireless network of your choice. The unlocked
If you don’t want a multiyear service contract or if you prefer to use a local carrier when traveling abroad, the unlocked iPhone is the best choice. It arrives without a micro-SIM card, so you’ll need an active micro-SIM card from any supported GSM carrier worldwide. To start using it, simply insert the micro-SIM card into the slot on your iPhone and turn it on by pressing and holding the On/Off button for a few seconds. Then follow the onscreen instructions to set up your iPhone.
iPad with Retina display comes in four storage sizes: 16GB, 32GB, 64GB, and 128GB.2 The term “GB” stands for gigabytes. The more gigabytes you have, the more content you can store on your iPad — apps, HD videos, movies, photos, books, magazines, and more. If, for example, you have a large music library or you frequently download HD movies, it’s a good idea to consider an iPad with a larger storage capacity. If you have a relatively small music or photo library or rarely make or buy movies, an iPad with a smaller capacity may be better for you. Of course, over time you will add more content to your iPad, so you’ll want to think about how your storage needs may evolve.
Wi-Fi model: Uses high-speed Wi-Fi networking to connect to the Internet. It’s ideal if you have a wireless Internet router in your home or if you’ll be using your iPad near a wireless hotspot in a coffee shop or school library, for example. There are Wi-Fi hotspots nearly everywhere around the world — iPad with Wi-Fi finds them automatically.
Wi-Fi + Cellular model: Keeps you connected to the Internet using a fast cellular data connection when Wi-Fi isn’t available. So you can stay connected when you’re commuting on the train, hanging out at the park, or looking for directions during a road trip. It’s available without a contract, and service is sold separately. See your carrier for rate plan information.
To start mobile data service, you will need a micro-SIM card and a data plan. A range of data plans are available and most don’t require a contract. Contact your wireless carrier for information on getting a micro-SIM and data plan.
