iPhone, iPad, iPod touch
Out of the box, the iPhone, iPod touch, and iPad are powerful devices with plenty of built-in features to satisfy your daily requirements for productivity and fun. Whether you're thinking about buying an iPad, a longtime user of the iPhone, or a brand new user of the iPod touch, a refresher course in the basics will come in handy. Out of the box, here's what you get when you purchase an iPhone, iPad, or iPod touch.
iPhone 4 & iPod touch (fourth generation)
The iPhone and iPod touch are similar in appearance and have many of the same features (see graphic above right). Of course, the iPod touch does not have a built-in cell phone. In addition, there are minor differences in the placement of buttons and ports, which are indicated in this graphic.
iPad (first generation)
Although much larger, the iPad has many similar hardware as the iPhone and iPod touch.

Both devices can record video at up to 720p HD. Earlier versions of the iPod touch have no camera at all.
Multi-touch display (all devices): The iPhone and iPod touch have 3.5-inch diagonal color touch screens with 960x640 pixel resolution. The iPad has a 9.7-inch diagonal color touch screen with 1024x768 pixel resolution. The iPhone 4 uses Apple's new "Retina Display," which has 326 dots per inch resolution; about four times the number of pixels as previous iPhone screens. The multi-touch display lets you select apps, type messages, dial phone numbers, and otherwise interact with your iOS device.
Dock connector (all devices): The iPhone, iPod touch, and iPad have identical 30-pin iPod dock connector ports on the bottom edge of the devices that let you connect to your computer and sync data, music, videos, and other files using the USB cable that ships with the devices. You also charge the device with this port, using the AC power adapter that ships with the devices.
Headphone jack (all devices): This headphone jack is a standard 3.5mm audio jack that you find in most audio devices. You can use your own headphones, but if you want to talk and listen at the same time, you'll need to purchase an add-on adapter with a microphone.
Home button (all devices): It's your shortcut out of the app you're using and it takes you to the Home screen. Pressing the Home button again will take you to the Spotlight search screen. For more on what the Home button can do, see page 20.
Microphone (all devices): The iPhone uses an internal microphone found at the bottom right corner of the device. It serves many purposes including making phone calls, recording voice messages, using voice control and more. The 4G iPod touch also has this microphone, and you can use it to record video and sound.
Processor (all devices): A4 processor capable of running at 1-GHz (actual speed varies between device types).
RAM memory (all devices): Used to run iOS and apps. iPhone 4, iPod touch gen 4: 512MB; iPad: 256MB RAM.
Receiver (iPhone only): Place your ear close to this to listen to incoming calls. (You can also use the headphones that came with your iPhone.)
Ring/Silent switch (iPhone, iPad): On the iPhone, this switch toggles between activating the ringer or putting your phone is silent mode. Since this switch only silences the ringer, you can still listen to music through the phone's speakers. With iOS 4.3, the switch toggles between screen orientation lock and silencer. When in silent mode, you don't hear any of the beeps and other sounds associated with opening and using the apps. Like the iPhone, you can still listen to music.
SIM card tray (iPhone, iPad with Wi-Fi + 3G): The tray accepts a micro-SIM card, which is needed to connect to AT&T's GSM network. SIM cards are not used with Verizon's CDMA network. If you ever need to eject the SIM card, you can do so by inserting the end of a paper clip into the tiny hole on the side of your device.
Sleep/Wake button (all devices): This turns the screen on and off to conserve power. The iPhone will still receive calls with the screen off, and all devices will continue to play music. Pressing the button again or pressing the Home button will turn the screen back on. To turn off your device completely, press and hold down on the Sleep/Wake Button until "slide to power off" appears; then move the slide to the right. Turn your device back on by pressing and holding down on the Sleep/Wake button. Press the Sleep/Wake button once to silence an incoming call on your iPhone, and press it twice to send the call directly to voicemail.
Speaker (all devices): The speaker is located at the bottom left edge of the iPod touch and the bottom right edge of the iPhone and iPad. It projects speakerphone calls on the iPhone as well as music, movie audio, and other sounds on all devices.
Storage memory & price (all devices): All iOS devices come with built-in flash memory to store music, videos, data, and other files. Current models available: iPod touch 8GB ($$229), 32GB ($299), 64GB ($399); iPhone: 16GB ($199), 32GB ($299); iPad with Wi-Fi: 16GB ($499), 32GB ($599), 64GB ($699); iPad with Wi-Fi +3G: 16GB ($629), 32GB ($729), 64GB ($829). The iPhone price requires a new 2-year wireless service contract with AT&T or Verizon Wireless. The iPad is sold without a service contract, but to use the 3G capabilities you will need to purchase a monthly service contract.
Volume up and down buttons (all devices): These buttons control the volume of calls, sounds, and audio/video playback.
Accessories that ship with iOS devices
Dock connector USB cable (all devices): Connects your iOS device to the power adapter or to a Mac or PC computer for syncing.
Documentation (all devices): Minimal getting started instructions are included. You can download full user guides in PDF format from Apple's website (support.apple.com/manuals).
Earphones (iPhone, iPod touch): The iPod touch ships with a standard set of white stereo earphones that connect via cable to the headphone jack. The iPhone ships with earphones with a built in mic, which can be used for phone calls or to listen to music. The iPhone's earphones (shown above) have a remote control built onto the cable that lets you adjust volume, change music tracks, and answer and end calls. The remote has some neat control features built into it: To pause playback, squeeze the control once. To resume playback, squeeze it again. To skip to the next track, squeeze it twice. To go back to the previous track, squeeze it three times. To send an incoming call straight to voice mail without answering it, squeeze and hold for a few seconds.
