- Step 1: Hold the phone Check out the iPhone 4's new design -- front and back glass panels with a stainless steel band wrapped around the edge. Outside, you'll find inputs, front and rear cameras, and volume and mute controls; inside is an updated A4 processor and a battery that's 16 percent larger than older iPhones.
- TIP: The metal band also functions as the phone's antenna.
- Step 2: See sharper images Press the home button to activate the device and turn on the iPhone 4's retina display -- it provides screen resolution with 4 times the pixel count of older iPhones and is perfect for digital reading, watching movies, browsing photos, or surfing the web.
- Step 3: Take a picture Open the camera app and use the 5-megapixel rear camera to take still photos and shoot high-definition video. In low light, enhance the picture with an LED flash.
- Step 4: Get FaceTime Make video calls. Connect to a wireless network and call another iPhone 4 user, and, as long as their phone's also hooked up to Wi-Fi, tap "FaceTime" to see them on your screen. Tap the camera icon to switch between the front and rear cameras and choose what you show the person you're talking to.
- Step 5: Switch between apps The iPhone 4's new software, iOS4, makes it possible to multitask. While using an app, double-tap the Home button to bring up a list of your apps on the bottom of the screen. Scroll to a second app and tap its icon to open and use it; at any point, double-tap again, open the original program, and pick up where you left off.
- TIP: iOS4 is also available for older iPhones, including the 3G and 3GS.
- Step 6: Download more Visit the app store to find even more apps and give the iPhone 4 the juice to power your life.
- FACT: Within 3 days of its 2010 launch, Apple had sold 1.7 million iPhone 4 phones.
