The interaction with the user is done through a touch-sensitive screen. Apple reported more than two hundred patents related to technology that created the iPhone.

The device is available for a price of $ 199 for the 8GB model or $ 299 for a 16GB at Apple Store and AT & T Mobility. Announced on January 9, 2007, the iPhone was launched on June 29, 2007 in the U.S. on 9 November 2007 in Germany and the UK, and November 29 in France.

For example, a song is gradually discontinued when the user receives a call. Once the call is ended the music gradually returns to play.

The iPhone includes a Visual Voicemail feature of ( 'Visual Voicemail') in partnership with AT & T Mobility, which allows users to see the current list of voice messages waiting. Unlike the other systems, messages can be heard out of order, just picking up the desired message in the list. AT & T completely reformed its infrastructure of Voicemail to accommodate this new feature developed by Apple.

SMS messages are presented chronologically in a mailbox, for very similar to Apple Mail, which places all the messages of the containers along with the answers. Text messages are displayed in balloons in comics (like iChat) under each name the recipients. In the January 1.1.3 update has been added to support multiple items of SMS.

The touch-sensitive screen HVGA (320 × 480 px at 160 ppi) with optical quality glass was specially created to be used with a finger, or multiple fingers for multi-touch sensitivity. You do not need a stylus pen, and none can be used, since the system is sensitive only to the capacitance of the human skin. For this reason, can sometimes be uncomfortable handling the device, as in cold regions where users have to take your gloves to use the touchscreen.

For text input, the device has a virtual keyboard on the screen, with a system of spelling, forecasting a dictionary of words and intelligent that has the ability to learn new words. For new users the system can be frustrating in the beginning, with failures of simple as pressing wrong keys and typing rhythm. Apple has released videos on their website explaining how to properly interact with the system.

The multi-touch can not only execute commands by tapping the screen, but go beyond, scrolling lists with the slide of the finger and zoom in and out images with the movement of the thumb forceps and the indicator. The screen is capable of recognizing simultaneous touches, allowing the phone recognize gestures and offer a richer interaction, allowing the user to 'manipulate' the objects. Steve Jobs showed the first public presentation of the product in January 2007, use of the feature to browse albums by cover of music (Cover Flow, use that existed in iTunes) to do the zooming of photos and maps and to explore pages in the Safari Web browser, focusing on specific pieces of the screen by moving the clamp of the thumb and index, and clearly stretches, such as photos or columns with a double tap of the finger.

The iPhone has a camera of 2.0 megapixels, which has no function or macro flash. The quality of the camera is highly criticized by experts in photography, consider that the very poor model for the resources that the phone offers. It is not possible to record videos and send the MMS, but with the unit unlocked and released for installation of third-party applications, you can install the application "Iphone Video Recorder, which records video of satisfactory quality.

The user can zoom in the pictures just stretching your fingers to move the clamp of the thumb and the indicator on the screen multi-touch. The software can interact with iPhoto, available on Macintosh computers.

Pictures of users around the world learned with the iPhone camera can easily be found using the Flickr.

Apple confirmed that an optimized version of the operating system Mac OS X (without unnecessary components) runs on the iPhone, but the differences between the operating system (OS X) running on Macintosh computers and the iPhone have not been officially explained. The iPhone has an ARM CPU, and the version of OS X that runs on the iPhone than the desktop version because it was written for the ARM architecture of instructions instead of x86 and PowerPC ISA in the version of OS X for Mac was written.

The operating system takes about 300 MB of total device in 8 or 16 gigabytes. This made him capable of supporting future applications from Apple, which plans to offer a simple and practical way to update the iPhone's operating system , in a similar fashion and clean the way in which Mac OSX and iPod are updated, and this is a great advantage when compared with other cell phones.
Widgets are similar to those available in the Dashboard of Mac OS X were included in the iPhone. They include information on market shares and widgets for weather and time.

The iPhone version of OS X also includes the software component of Core Animation, which is responsible for the smooth animations used in the user interface. Core Animation is part of Mac OS X v10.5.

The version of OS X on iPhone is apparently a "OS X 1.0 (1A543a), as was seen in a log of a crash in the application MobileMail. The application was apparently being run as a super user.

Apple launched the iPhone 3G along with the App Store. Shop online for games and applications developed by third parties. The developers use the tools provided by the SDK to develop applications for both the iPhone (in its two versions) and for iPods Touch. Applications can be downloaded through the device (application of up to 10 MB) or from iTunes. Prices are set by the developers, and 70% of the application is with him, and 30% goes to Apple. The App Store is available in Brazil since the launch of the iPhone 3G, but presents a collection of little applications when compared with the U.S. App Store. One of the factors that support for this shortage is the fact the Brazilian App Store, there the "Games". What causes this is that the prosecutor requires the assessment and classification of age restriction is made for them, do not accept the American classification. In just over six months since the opening of the App Store, Apple announced that it was downloaded over 500 million applications for iPhones and iPod touch. Today, there are 15 thousand titles in store, divided into 20 categories - from games to applications for business.
