Congrats! You're up and running with the iPhone 4. Here's how to start getting the most out of your new mobile device and its features.
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.
