Mobile technology is the technology used for cellular communication. Mobile code division multiple access (CDMA) technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld game console. Many experts argue that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers is becoming more popular. The most popular tablet at the moment is the iPad, by Apple. Tablets are available on the 3G and 4G networks.

iOS - Introduction
• iOS is Apple’s mobile operating system derived from Mac OS X.
Developed originally for iPhone it has since been shipped on the
iPod Touch and iPad as well.
• In iOS, there are four abstraction layers:
• The core OS layer, The core services layer, The Media layer, The
Cocoa touch layer.
• The iPhone SDK contains the code, information and tools which
need to develop, test, run, debug and the applications for iOS.
• The Xcode tools provide the basic editing, compilation, and
debugging environment for the code, Xcode also provides the
launching point for testing applications

iOS – Development Tools
• The release of Xcode 3.1, Xcode is the development environment for the
iOS SDK. IPhone applications, like iOS and OS X, are written in
Objective-C, Action Script, Xcode, Flash
Builder, Flash, Photoshop, Blender, Eclipse, Java, Microprocessor
programming (Propeller, BASIC, and PIC), Cocoa, Agile, Usability, Web
Services, JavaScript, jQuery, Social Web Trends and MXML. IOS based on

• Android is Based on Linux Kernel.
• Developed by Google and later open Handset Alliance.
• Open Source under the Apache 2 License.
• Android is kernel based on the Linux kernel 2.6 and Linux Kernel
3.x (Android 4.0 onwards), with middleware, libraries and APIs
written in C, C++, Java. Architecture: ARM, MIPS, Power
Architecture, x86. Package manager: APK.

BlackBerry OS
• BlackBerry OS developed by Research in Motion (RIM).
• The BlackBerry platform is perhaps best known for its native support
for corporate email, through MIDP 1.0 and, more recently.
• A subset of MIDP 2.0, which allows complete wireless activation and
synchronization with Microsoft Exchange, Lotus Domino, or Novell
GroupWise email, calendar, tasks, notes, and contacts, when used with
BlackBerry Enterprise Server. The operating system also supports WAP
1.2.
• The OS provides support for Java MIDP 1.0, WAP 1.2. Kernel type:
Java virtual machine
• Third-party developers can write software using the available
BlackBerry API classes, although applications that make use of certain
functionality must be digitally signed.
• C++ Standard Library or Java API contained in the JDK or JRE, of one
of the editions of the Java Platform. The three editions of the Java
Platform are Java ME (Micro edition), Java SE (Standard edition), and

Windows Phone
• Windows Phone is a family of mobile operating systems developed
by Microsoft
• Microsoft created a new user interface, featuring its design language
called Modern Style UI.
• Metro is an internal code name of a typography-based design
language created by Microsoft, originally for use in Windows Phone
7. Early uses of the Metro principles began as early as Microsoft
Encarta 95 and MSN 2.0, and later evolved into Windows Media
Center and Zune.
• Package manager: Zune Software, from various independent
developers made using XNA Game Studio or OpenZDK, which use
C# and C++ respectively
• Kernel type: Monolithic (Windows CE) (Windows Phone 7), Hybrid
(Windows NT) (Windows Phone 8)
• Supported platforms: Qualcomm Snapdragon (Based on ARM V.7
or later)

Symbian
• Symbian switched to using standard C++ with Qt as the main
SDK, which can be used with either Qt Creator or Carbide.c++.
• Qt supports the older Symbian/S60 3rd (starting with Feature Pack
1, aka S60 3.1) and Symbian/S60 5th Edition (aka S60 5.0)
releases, as well as the new Symbian platform. It also supports
Maemo and MeeGo, Windows, Linux and Mac OS X
• Application development can be done using Python (see Python for
S60), Adobe Flash Lite or Java ME.
• Symbian devices can also be programmed using Python, Java
ME, Flash Lite, Ruby, .NET, Web Runtime (WRT) Widgets and
Standard C/C++. Visual Basic programmers can use NS Basic to
develop apps for S60 3rd Edition and UIQ 3 devices.
