Back Camera and LED Flash
On the back of the iPhone 5 is the second of two cameras, as well as an LED flash. The camera sports an 8-megapixel CMOS backside illumination sensor, which snaps pictures at 3264-by-2448-pixel resolution. (In real-world terms, that would translate to a high-quality 8-by-10-inch glossy print.) An attached hybrid IR filter provides better color accuracy, while the f/2.4 aperture offers improved low-light performance. The iPhone 5 camera sports a sapphire lens cover for sharper images. The iPhone's back camera also captures 1080p high-definition video at up to 30 frames per second, with real-time video image stabilization and temporal noise reduction.
The Ring/Silent switch--found on the left side of the device--does pretty much what you'd suspect: Flick it backward to silence the phone, forward to activate the ringer. When you switch to Silent mode, you reveal a small orange stripe on the switch, and your device vibrates. Silent mode silences only rings and alerts, however; you can still play music and game sounds through the speaker.
Volume Up and Volume Down Buttons
Directly below the Ring/Silent switch is a pair of volume buttons. Press the plus-sign button (+) to increase volume and the minus-sign button (--) to decrease volume. In the Settings app, you can choose whether these buttons affect only noises from an app, or whether they control systemwide sounds as well. In the Camera app, the plus-sign button also works as a physical shutter button.
SIM Card Slot
The new iPhone can operate on multiple cellular bands, thanks to its dynamically switching on-board radio: various bands of the LTE cellular data standard, HSPA+, DC-HSDPA, GPRS, EDGE, CDMA-EvDO, and HSPA. Major U.S. partners for the iPhone 5 include AT&T, Sprint, and Verizon.
When you purchase a new iPhone, you can do so in one of two ways: with a cellular carrier contract or contract free. The first option lets you receive a significant discount on the phone, but you have to use your iPhone solely with that carrier for two to three years, depending on your carrier and region. Contract-free phones allow you to use any carrier's pay-as-you-go plan but are several hundred dollars more expensive up front. Either way, you'll need a carrier to talk on your iPhone and use cellular data.
Your iPhone needs a nano-SIM card to connect to a cellular provider. Without it, you won't be able to access call networks or cellular Internet, only Wi-Fi. If you sign up for a contract when you purchase your device, this SIM card comes preinstalled. You can see Apple's full list of supported spectrum bands on Apple's iPhone webpage under "Cellular and Wireless."
If you have a contract-free phone and need to install a nano-SIM--or you need to access your current nano-SIM card--you can remove it by sticking one end of a paper clip into the hole next to the SIM card slot.
Your device comes equipped with a set of earbuds with a microphone and remote built onto the right-side cable that can control volume, change tracks, and answer and end calls. You can use these controls to perform a variety of actions with the right combination of taps.
Single-Click: Clicking the center button of the remote once while listening to music or watching a video pauses playback; if you're receiving a call, a single-click answers it, and another single-click hangs up when you're finished.
Single-Click and Hold: When you're receiving an incoming call, a single-click and hold declines the call and sends it directly to voicemail; while you're on a call, you can do this to switch to a secondary call. Otherwise, holding down on the remote activates Siri.
Double-Click: Squeeze twice, and your song skips to the next track.
Triple-Click: Squeeze three times to skip back to the previous track.
Transfer your data
You've moved to the latest and greatest in the iOS world, and to do so, you're leaving your old device behind. But before you send it off on its last voyage, you have to decide whether you want to transfer its data to your iPhone 5. Here are the various ways to do so, depending on whether you're moving from an old iPhone, a different smartphone, or a feature phone.
Upgrade from an older iPhone
If you're upgrading from an older iPhone, you can transfer all its apps, data, and settings to your iPhone 5. But to do so, you'll need to make a backup (via iTunes or, if you're running iOS 5, via iCloud) of your information.
Make a backup using iTunes: If your old device is running iOS 4 or earlier, an iTunes backup is the way to go. To update your backup (or to create a new one) connect your old device to the computer you normally sync it with via USB, open iTunes, select the device, and press the Sync button. You can also create a backup by control-clicking on the device in the iTunes Source List and selecting Back Up from the drop-down menu.
Make a backup using iCloud: If you're running iOS 5 or iOS 6 on your old device and you have an iCloud account, you can alternatively take advantage of iCloud Backups to save your data. Your device will automatically make an iCloud backup once a day while locked, plugged in, and connected to a Wi-Fi network, but you can manually force a backup whenever you're on Wi-Fi by opening the Settings app on your device. Navigate to iCloud > Storage & Backup, and make sure the iCloud Backup switch is toggled on. From there, you just have to tap on Back Up Now to start the process. (You should note that iCloud backups can sometimes take significantly longer than iTunes backups, so it may not be the best option if you're in a hurry to set up your new phone.)
Upgrade from another smartphone
Moving from an Android, BlackBerry, or Windows smartphone to the iPhone 5? Depending on how you've set your information up, it should be relatively painless to transfer it to your new device.
