You already have it, it's in your hands, you new and brand new iPhone 4. But… So now what? Simple, now is when you have all the questions you have and to have. How does I put this thing in silence? Where Is that game so cool that my brother-in-law taught me? How do I add new shades? There is no problem. That is what we are here for. To help you, because from now on we start from scratch. As we move forward we will get into the iPhone operating system (iOs) until we link up with our colleague Gonzalo who is waiting for us at the other end, waiting for us, once we control our iPhone, we can make much more advanced changes and improvements, such as modify the operating system through the famous Jailbreak. But for that we must know perfectly the main functions that it brings from the factory, which are not few. As we go forward, if questions arise, you can leave your comments so that we can solve all the questions that may arise, or You can write to me at [email protected]
Today to begin, and getting into the matter, we are going to see a descriptive image of iPhone 4 (The previous models may have some deficiency with respect to this).
As you can see in the image, the iPhone 4 consists of:
- Headphone jack: Standard 3,5mm, that is, any "headset" would be worth it, which is not hands-free (it depends on the manufacturer and what the aforementioned carries inside), those of a lifetime, those of the Walkman that went battery operated, that you had to turn the tape, what times those ...
- Microphone top: iOs 4 theoretically contrasts the information from this mic with the bottom one and removes noise to capture cleaner sound information.
- Standby button or «Hold Button»: Allows us to turn off or turn on the iPhone, in addition to blocking the screen or reactivate the terminal.
- Tone / mute switch: Many people do not know that this button exists, even after one or two months, so do not be scared when you realize that on the iPhone, silence works by hardware, with this little button, and not by software.
- Volume buttons: Obviously to raise and lower the volume.
- VGA front camera: with less resolution than the later one, something that, in my opinion is important, since it is mainly used to make video calls, through Skype (yes, Skype also exists for iPhone) or FaceTime, and the fact that it has less resolution gives us allows you to make such a video call with a more limited bandwidth. For example, if you are in a town, on vacation, one of those in which they ask you what a Smartphone is, where the coverage that arrives, hopefully, is that of water, and you find coverage more than to connect with difficulty to internet, you could not get to establish a video call if it were of higher quality. With VGA yes. Attest.
- Retina display: High definition screen created especially for iPhone 4.
- Start button or «Home Button»: With it we can exit an application with a single press, or if we press twice in a row, it opens the multitasking bar, which is where the applications "minimized" or "in the background" are left. We can also hold down this button to open voice control, also called "Voice Over"
- Main camera: This camera allows us to take photos of 5Mpx (megapixels) or take high definition videos of up to 720p, (1280 × 720 pixels).
- Led Flash: The iPhone incorporates an LED flash, which allows us to take photos when there is little lighting. This flash can also work as a flashlight since there are programs that allow us to use it for this purpose.
- Status Bar: At the top of the screen there is a band in which, by means of indicators, we can know in what state our iPhone is. Some of the data that it provides us are network coverage, 3G coverage, time, battery status, as well as some services that may be working such as the alarm, bluetooth or screen rotation lock.
- Receiver: It is the earpiece through which we will listen to telephone conversations.
- App icons: A program or application is called an App in Apple circles. These icons represent those applications and can be grouped into folders.
- Sim card tray: To eject this card, all you have to do is insert the tool that comes with the box. A paper clip can also be used for the same purpose. Simply insert it and squeeze without fear, but without forcing, until the tray is automatically ejected.
- Dock connector: At the bottom of the phone, between the microphone and the speaker, we find the «Dock» connector. This connector will allow us to charge the iPhone, as well as synchronize it with our computer to load new content, such as music, photos or applications. There are countless accessories on the market created especially for iPhone or iPod that incorporate this connection.
- Additionally, the iPhone incorporates other sensors that are not visible to the naked eye and that we will gradually analyze, such as the sensors of moisturesensors proximitysensors lighting environmental, accelerometers y Gyroscope.
If up to now you have had any doubts, do not worry, I remind you that you can ask absolutely anything.
