iPhone is a new generation of cell phones, 3G is the second generation of iPhone, a smartphone made by Apple that combines an iPod, a tablet PC, a digital camera and a cellular phone. You will learn a few thing on how to get start with your iPhone if you just bought one. iPhone is all most the same thing as the iPods it comes with a standard audio jack of 3.5mm instead of the 2.5mm found on most cell phones. Unfortunately the jack is buried a little into the handsets body, making this incompatible to most headphones you may own. The iPhone has an internal microphone this is found at the right bottom of the phone, used only to make calls and it is unable to record any external audio. The headset works exactly as the iPod’s earbuds, you are able take calls through it and listen to the audio from its YouTube videos and iPod program. The headset is different from the iPod ones; it has a tiny microphone which is attached to a cable that’s dangling from the right earbud, making it possible to hear voice during a call when it’s plugged in. The headset comes with a built in switch you can press the microphone once when watching a video or listening to music to playback or pause. Press twice to skip a track, if you receive a call you can press the microphone once to answer and end a call. If you want to send a call to voice mail then press and hold for a couple of seconds. It will beep twice once it’s done. You can also take one call and put the other on hold, or go back to the call on hold. The iPhone comes standard with 30-pin iPod port connector to connect to you computer or your other accessories. Due to the different shape from the iPod it might not fit well in several accessories. Interference from the iPhones antenna may not allow the speakers to work except in airplane Mode. At the left bottom edge of your iPhone resides the speaker, the sound comes from here if you have a call on the speakerphone. It also plays the video and music audio on your phone. Since it has only one speaker it only plays audio in mono meaning single channel.
Such as all current GMS phones, this iPhone also uses a SIM card. At the top of your phone you will find a little slot for the SIM card. The iPhone comes preinstalled with the SIM card and activates through iTune. Unfortunately you won’’t be able to use your old phone SIM card in the iPhone it won’t work because the iPhone SIM card has new and special characteristic which are not in other SIM cards.
OFF/ON AND WAKE/SLEEP SWITCH
Rounding on the top is the on/off and sleep/wake button, this switch has four functions. You can press the swish briefly this will lock your screen, but the phone can still play music and receive calls, just the screen will be off. If you press this button again you will unlock or wake up the iPhone, to shut the phone off completely then hold down the button for some seconds. Once the phone is shut down it won’t play music, ring or anything else. To reactivate the phone you just have to press the button again.
