The iPhone uses Apple's Lightning dock connector to connect to your computer and other accessories. Unlike Apple's older 30-pin connector, it's reversible, so you can plug it into your phone in either direction. It won't work with older 30-pin third-party accessories without an adapter.
On the bottom right of the new iPhone is a small speaker that's responsible for projecting speakerphone calls, music, movies, game noises, and any other miscellaneous noise. Because your device has just one speaker, it plays all audio in mono (on a single channel).
Back Camera and LED Flash
On the back of the iPhone is the second of two cameras, as well as an LED flash.
The iPhone 5c sports an 8-megapixel CMOS backside illumination sensor, which snaps pictures at a 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 iPhone 5s's camera has improved internals, including an 8-megapixel sensor with larger individual pixels (for clearer low-light photographs), an f/2.2 aperture, and a TrueTone dual-LED flash for warmer pictures when using a flash. The back camera also records 1080p high-definition video at up to 30 frames per second and 720p video at up to 120 frames per second, with real-time video image stabilization and a 3x digital zoom option.
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 button (+) to increase volume and the minus button (--) to decrease volume. (In the Camera app, the plus button also functions as a physical camera shutter button.) In the Settings app, you can choose whether these buttons affect only noises from an app, or whether they control systemwide sounds as well.
SIM Card Slot
The 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 5c and 5s include AT&T, Sprint, and Verizon.
