iPhone, iPad & iOS
Assistant Lecturer Sama Salam Samaan
o The iPhone is a line of Internet and multimedia-enabled smartphones marketed by Apple.
The first iPhone was unveiled by Apple's former CEO Steve Jobs on January 2007. The 5th
generation iPhone, the iPhone 4S, was released on October 14, 2011.
o An iPhone can function as a video camera ,a camera phone, a portable media player, and
an Internet client with email and web browsing capabilities, can send texts and receive
visual voicemail, and has both Wi-Fi and 3G connectivity.
o The user interface is built around the device's multi-touch screen, including a virtual
keyboard rather than a physical one.
oThe iphone apps have diverse
functions, including games, GPS
navigation, social networking, security
and advertising for television shows,
films, and celebrities.
o There are five generations of iPhone
models. The original iPhone was a GSM
phone that established design
precedents like screen size and button
placement that have persisted through
oThe iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS
added a faster processor, and higher resolution camera, including video recording at 480p.
oThe iPhone 4 has a rear facing camera (720p video) and a front facing camera (at a lower
resolution) for FaceTime video calling and for use in other apps like Skype.
o In 2011 the iPhone 4 was voted the Best Mobile Phone On Earth. The iPhone 4 featured a
higher-resolution 960x640 display; it was released on June 2010.
o On October 2011, Apple announced the iPhone 4S. The iPhone 4S added a higher
resolution camera (8 megapixel) with 1080p video recording, face detection, and video
stabilization, a faster, dual core processor, world phone capability (allowing a single handset
to operate on networks based on both GSM/UMTS and CDMA technologies), and a natural
language voice control system called Siri.

o Internet access is available when the iPhone is connected to a local area Wi-Fi or a wide
area GSM or EDGE network, both second-generation (2G) wireless data standards.
oThe iPhone 3G introduced support for third-generation UMTS .
o By default, the iPhone will ask to join newly discovered Wi-Fi networks and prompt for
the password when required. The iPhone will automatically choose the strongest network,
connecting to Wi-Fi instead of EDGE when it is available.
o The iPhone 3GS has a maximum download rate of 7.2 Mbit/s. Furthermore, email
attachments as well as apps and media from Apple's various stores must be smaller than
20 MB to be downloaded over a cellular network.
o Larger files, often email attachments or podcasts, must be downloaded over Wi-Fi
(which has no file size limits).
o If Wi-Fi is unavailable, one workaround is to open the files directly in Safari.
o Safari is the iPhone's native web browser, and it displays pages similar to its Mac and
oThe maps application can access Google Maps in map, satellite, or hybrid form. It can
also generate directions between two locations, while providing optional real-time traffic
o iPhone users can and do access the Internet frequently, and in a variety of places.
According to Google, in 2008, the iPhone generated 50 times more search requests than
any other mobile handset.
o iOS (formerly known as iPhone OS) is Apple's mobile operating system. Originally
developed for the iPhone, it has since been extended to support other Apple, Inc. devices
such as the iPod touch, iPad and Apple TV.
o Apple, Inc. does not license iOS for installation on third-party hardware.
o Recently, Apple, Inc.'s App Store contains more than 500,000 iOS applications, which have
collectively been downloaded more than 18 billion times.
oThe user interface of iOS is based on the concept of direct manipulation, using multi-touch
gestures. Interface control elements consist of sliders, switches, and buttons.
o iOS is derived from Mac OS X, and is therefore a Unix-like operating system by nature.
o In iOS, there are four abstraction layers:
• Core OS layer,
• Core Services layer,
• Media layer, and
• Cocoa Touch layer.
oThe current version of the operating system (iOS 5.0) uses roughly 774.4 megabytes of the
device's storage, varying for each model.
The iOS home screen contains these default "apps".
Some of these applications are hidden by default and
accessed by the user through the Settings app .
• Phone: Telephone, FaceTime video calling.
• Mail: E-mail client.
• Safari: web browser.
• iPod: portable media player.
• Messages: Text messaging, MMS, iMessage .
• Calendar: Calendar.
• Photos: Photo viewer
• Camera: Camera, Camcorder
• Clock: World clock, stopwatch, alarm clock and
• YouTube: YouTube video streamer
• FaceTime: Video calling
• Siri: Voice control assistant
• Maps: Google Maps
• Notes: A simple note-taking program
• App Store: To buy iOS apps
& more than 500,000 app.
o Before iOS 4, multitasking was limited to a selection of the applications Apple included
on the devices. Apple worried that running multiple third-party applications
simultaneously would drain batteries too quickly.
o Starting with iOS 4, on 3rd-generation and newer iOS devices, multitasking is supported
through seven background APIs:
1. Background audio - application continues to run in the background as long as it is
playing audio or video content.
2. Voice over IP - application is suspended when a phone call is not in progress.
3. Background location - application is notified of location changes.
4. Push notifications
5. Local notifications - application schedules local notifications to be delivered at a
6. Task completion - application ask the system for extra time to complete a given
7. Fast app switching - application does not execute any code and may be removed
from memory at any time.
oThe iPad is a line of tablet computers designed, developed and marketed by Apple Inc.,
primarily as a platform for audio-visual media including books, movies, music, games, and
o Its size and weight fall between those of contemporary smartphones and laptop
oThe iPad runs the same operating system as the iPod Touch and iPhone —(iOS)—and can
run its own applications as well as iPhone applications.
oWithout modification, the iPad will only run programs approved by Apple and distributed
via the Apple App Store.
o Like iPhone and iPod Touch, the iPad is controlled by a multitouch display—a departure
from most previous tablet computers, which used a pressure-triggered stylus—as well as a
virtual onscreen keyboard in lieu of a physical keyboard.
o Apple released the first iPad in April 2010, and sold 3 million of the devices in 80 days.
During 2010, Apple sold 14.8 million iPads worldwide.
o By the release of the iPad 2 in March 2011, more than 15 million iPads had been sold.
oThe iPad can use Wi-Fi to provide location information to applications such as Google
o The 3G model supports A-GPS to allow its position to be calculated with GPS or relative
to nearby cellphone towers; it also has a black strip on the back to aid 3G reception.
o The 3G iPad can be used with any compatible GSM carrier, unlike the iPhone, which is
usually sold 'locked' to specific carriers. A SIM lock, network lock or subsidy lock is a
capability built into GSM phones by mobile phone manufacturers. Network providers use
this capability to restrict the use of these phones to specific countries and network
Power and battery
oThe iPad uses an internal rechargeable lithium-ion polymer (LiPo) battery.
Apple claims that the battery for both generations of iPad can provide up to 10 hours of
video, 140 hours of audio playback, or one month on standby.
o Like any rechargeable battery technology, the iPad's battery loses capacity over time.
o The iPad was released with three capacity options for storage: 16, 32, or 64 GB of internal
flash memory. All data is stored on the internal flash memory, with no option to expand
o Apple sells a "camera connection kit" with an SD card reader, but it can only be used to
transfer photos and videos.
o Like the iPhone, with which it shares a development environment (iPhone SDK, or
software development kit),the iPad only runs its own software, software downloaded from
Apple's App Store.
oThe iPad runs almost all third-party iPhone applications, displaying them at iPhone size or
enlarging them to fill the iPad's screen.
oDevelopers may also create or modify apps to take advantage of the iPad's features.
Application developers use iPhone SDK for developing applications for iPad.
o While the iPad is mostly used by consumers it also has been taken up by business users.
Some companies are adopting iPads in their business offices by distributing or making
available the iPads to employees.
o Examples of uses in the workplace include attorneys responding to clients, medical
professionals accessing health records during patient exams, and managers approving
o A survey shows that iPad usage in office workplaces is linked to the goals of increased
employee productivity, reduced paperwork, and increased revenue.
The iPad has several uses in the classroom, and has been praised as a valuable tool for
oThe iPad has also been called a revolutionary tool to help children with autism learn
how to communicate and socialize more easily.
In sports, new technology proposes the viewer to choose its alternative angles while
watching the game.
The iPad is able to support many music creation applications in addition to the iTunes
music playback software.
The iPad has introduced a new way watching television. The second screen expression is a
consequence of the media multitasking which is exploding.
