On/Off (Sleep/Wake): Switching the iPhone on and off is similar to other multimedia phones, but the same on/off button has many other functions to offer. This button is situated at the top-right edge of the phone. It's a black plastic button that is similar to a 'dash' in shape. By tapping it once, you can put the phone on standby mode that will turn off the screen, which will in turn, consume less power. You will be able to receive a call even when the phone is in standby mode. Tapping it again will view the screen to carry out other functions.
Pressing the button for three seconds will ask for your confirmation to switch off the phone by displaying a screen with a 'Slide to Power Off' option. You can then place your fingertip on the red right-pointing arrow and slide it to the right, which will turn off the phone completely. You wouldn't be able to receive calls or use any functions of the phone. To turn the phone back on, keep the switch pressed for a second, which will boot the device and the Apple logo will be displayed. When there is an incoming call alert, tapping it once can silence the ringing or vibration and tapping it twice will immediately send the call tovoicemail.
Navigation: There is a home screen button below the screen which takes you directly to the home screen, no matter where you are in the menu. The navigation on the iPhone is mostly by fingertip. Up to nine home screens can be created for quick access. You can customize the screen by arranging the icons and also moving them to another home screen. If you need to view the contents that are in options, you need to tap on the icon for a screen to appear, which will display the contents. If the displayed content is larger than the screen, you just need to slide your fingertip on the screen in the appropriate direction to view the rest. The screen only works with a fingertip, and not with a stylus or fingernail, like other touchscreen phones. You can zoom in photographs, maps, mails or the web by placing two fingertips on the point which you need to zoom into, and stretch them in opposite directions. The method of navigation on the iPhone is interesting for a new user, and is also very convenient once a user gets used to it.
Volume Control: On the left edge of the iPhone, there is an up/down volume switch which works in different ways. When on a call, the button adjusts the speaker or the ear bud volume. It adjusts the playback volume when listening to music. It is also like a central volume control button for other functions that need volume control.
Incoming and Outgoing Calls: By tapping the green 'Call' button located at the bottom of the screen, you obtain a list of contact information which you can scroll through, with your fingertip. You can also tap a number that is part of an SMS, email, contacts or favorites to make a call. If you have many phone numbers in your contact list, you can always use the search feature. You can even talk to more than one person at a time, switch between calls or create a conference call. To answer a call, press the 'answer' key located at the bottom of the screen.
On-screen Keyboard: The on-screen keyboard is the only way to type on the iPhone. The keyboard appears automatically when you tap in a place where typing is possible; like notes, SMS, text boxes, email, address bar, etc. While typing, the phone suggests options for the words you type. Text messages are displayed on the iPhone as an ongoing chat, which helps the user recollect the earlier messages and continue with the conversation. This is also known as a thread. The built-in dictionary suggests corrections in case content is typed incorrectly. If you need the 'caps lock' feature, turn on 'Enable Caps Lock' in the 'Settings' program. If you double-tap the 'L' key, after you have turned on the caps lock option, the key turns blue. It indicates that you are in the caps lock mode. To turn off the caps lock, just tap the 'L' key again.
Camera: An iPhone has a 2 mega-pixel camera that can be activated with a tap on the 'camera' icon from the main screen of the phone. You can rotate the view finder of the phone in any way in order to create the correct screen angle to take a picture. To click a picture, you need to press the 'Camera' icon at the bottom of the view screen. You need to select the 'photo' icon on the main page, which looks like a sunflower, to view all the images.

Songs on the iPhone can be sorted by artist's name, genre, playlists, etc. You can simply select the 'iPod' option on the screen to listen to music on the iPhone.

There is an address bar at the top of the browser where you can type the web address. To get a full browsing experience, turn the iPhone sideways, which will rotate the screen view to a wide-screen mode. Turn it back to a vertical position for a normal view. To zoom in on any content of the web page, double-tap it; and to zoom out, double-tap it again. You can scroll the page by dragging the fingertip up, down or sideways.
