And through the Internet connection will allow you to manage all your affairs, such as receiving and sending e-mail, and connect with friends on Facebook and Twitter, as well as take advantage of the applications of the device and that facilitate your life. External The iPhone with its large screen and large size fits your pocket easily without suffering, as it is very very high. It has only one button you press to control a number of tasks, otherwise it is controlled by touch. The iPhone is a touchscreen phone with only hands. Its colors are either black or white. The device is available in multiple capacities of 16 GB, 32 and 64. I think that the 32 is the most suitable for all uses. IPhone OS or iOS operating system is a system that is taken from the operating system in Macentos [1] and is beautiful as smooth and light on the device. The device supports writing and reading in Arabic. IPhone OS update is done through iTunes, which can be downloaded for free on your computer. It can also be updated directly from the iPhone by internet connection. When the operating system is updated, iTunes downloads a backup copy of all the programs in it and then displays the option to restore it after the update. Finally, before buying your iPhone, you need to make sure that it is unlocked. If it is the opposite, you will only be able to use it as a cellular phone after unlocking it. The phones purchased from the accredited telecommunications companies in the Arab countries [2] do not need to be unlocked because they are officially opened (officially unlocked). You can also turn off protection (which is optional for you) so that you can install software and applications available outside the Apple Store. The cancellation process is called jealbreak. Weaknesses 1. The device does not have a keyboard to write and connect to your friends, but depends entirely on touch. This may be a problem for a class of people. 2- The price is exaggerated. There are many competing phones with specifications that may be better but at a lower price (eg Samsung devices). 3. Bluetooth does not support receiving and sending files. But it can be skipped through the Gilberk. Update 20/2/2010: I found that many people enter the blog every day by searching for the phrase "iPhone" so I decided to add the following.
