This document summarizes the history and development of major mobile platforms: 1. The first mobile operating system, Palm OS, launched in 1996, followed by versions from Palm, Microsoft, and Symbian between 1997-2000. 2. Major developments between 2003-2011 included Windows Mobile, iOS, Android, and Blackberry OS versions. Platforms evolved from basic apps to advanced features and app ecosystems. 3. Key platforms discussed are Symbian, Blackberry OS, iOS, and Android. Symbian was an early leader used by Nokia. Blackberry OS powered Blackberry devices. iOS and Android now dominate the market.

1. Topic: Development of mobile application
Development and research of the topic
According to the proposed topic in the last draft and the subtopics that I will research;
at the moment I am making the summary of information about the following topics:
History of development in mobile, also I am researching about the evolution of
the different platforms or Mobile Operating Systems. In the next paragraphs I
will give to knowing a short abstract of the topics that I researched.
I am consulting information to depth about the implementation of the most
important mobile platforms that had allowed innovate the labor field and the
life of the men with the development of apps.
For this second draft, I will exhibit a brief explanation of every one of subtopics written
above.
Research summary of the topic (theoretical setting)
1. History of development in the mobile platforms
The massive development of mobile apps was generated from last eight years or
last ten years because although the cell phone began to appear from 40's, was
from 1996 that was created the first mobile operating system and in 2005 the
operating systems evolved to a technology very high that allowed create diverse
apps for different tasks besides conventional applications that was created initially,
for example (calculator, diary, messages, etc).
This is a brief summary of the important aspects in the history of development of
mobile platforms:
In 1996, the Palm company launched the first mobile operating system
called Palm OS 1.0, this system contained apps of RIM Company (Blackberry
company), for example: emails, diary, memo pad and task.
Between 1997 and 1998, the Palm company launched others two versions
(2.0 and 3.0). These versions didn’t change much with the exception of that
managed Web Support and interface with colors of 8 bits.
In 2000 changed the operation of operating systems with the Microsoft
creation called Pocket 2000 that later would have apps as: Messenger app
and Media Player 8 Enhanced UI.
Also in that year was created the Symbian operating system that was a
system implemented in mobiles as: Nokia, Sony Ericsson, Psion, Samsung,
Siemens, Benq, Lg, Motorola, Lenovo, Sharp, Panasonic, etc. This has
common applications of the time, but later this will allow the games
development and java applications, specifically with Java ME and J2ME
(programming languages).

2. In 2003, Microsoft created the operating system called Windows Mobile
with Bluetooth support and Internet Explorer browser.
In 2004, the Palm company launched the Palm Os Cobalt, this was
characterized for has wifi connectivity and Bluetooth.
From 2005 the history of mobile development generate other advance
because in this moment was leading the operating systems: Microsoft
(Windows Mobile 5) and Blackberry (Blackberry OS 4.1). Also an important
fact was the purchase of Android Inc for Google Company.
In 2007 Apple go in market with the launch of iPhone OS (iOS).
In 2008, Google Company launched to the market your first cell phone with
Android.
In 2009, the versions of iPhone and Android advanced technologically and
in this moment iPhone had iPhone OS 3.0 version and Android had (1.1, 1.5,
1.6, 2.0 and 2.1) versions. Also Microsoft competed with the Windows
Mobile 6.5 and Balckberry competed with BB OS 5 version. In this year
Hewlett Packard (HP) launched your operating system called HP Web OS.
In 2010 and 2011, Android created the 2.2 and 2.3 versions, this versions
are very important in nowadays because these are running in mobiles of
low range and low-media range. Microsoft launched Windows Mobile 7.
Blackberry created the Blackberry OS 6 version and Symbian try to follow in
the market when created the Symbian^2 and Symbian^3 versions.
Nowadays, the mobile platforms more important in the market are: Iphone
OS, Android, Windows Phone (this is a evolution of Windows Mobile) and
Blackberry OS.

2. Important Mobile Platforms
SYMBIAN
Is a operating system that was produced in a alliance of different companies of
mobile telephony, for example: Nokia, Sony Mobile Communications, Psion,
Samsung, Siemens, Arima, Benq, Fujitsu, Lenovo, LG, Motorola, Mitsubishi
Electric, Panasonic, Sharp, etc. Your origin came of EPOC32 that was used in
PDA's and Handhelds of PSION.
The objective of Symbian was creating an operating system for mobiles that
could compete with the operating system of Palm Company or Windows
Mobile, Android systems and iOS of Apple Inc. and Blackberry OS.
In 2011 was confirmed that this system just would give support to 2016 for this
operating system.
BLACKBERRY OS

3. Is a mobile operating system developed for RIM Company (Research In Motion)
for your cell phones and smart phones (Blackberry). This system is multi-task
and according to your mobile devices, this operating system accepts
management for trackwheel mechanism, trackball and touch.
Your development is originated of the firsts handheld in 1999. These devices
allow the access to emails, web browser and sync with programs as Microsoft
Exchange or Lotus Notes in addition of making functions of mobile device.
To Difference of Blackberry, existed others devices that used emails apps of
Blackberry OS, for example: Siemens, HTC, Sony Ericsson.
The mobile devices that use this operating system is orientate for professional
use or corporate use.
IPHONE OS (iOS)
Is a mobile operating system of Apple Inc; initially, this was developed for cell
phone (iPhone), but after was used in different devices as: IPod Touch and
Apple TV.
The iOS interface is based in the concept of direct manipulation, use touch
motion.
iOS is derivative of Mac OSX, also it`s derivative of Darwin BSD and for this
reason, this is an Unix operating system.
The applications must be written and compiled specifically for AMD Architect
(operating system architect), the applications developed for Mac OSX can’t use
in iOS for the differences in the architect.
ANDROID
Is an operating system based in Linux; mainly, this is design for mobiles with
touch screen as smart phones, tablets, etc. Android Inc. was support by Google
Inc., later in 2005 Google Inc bought the Android Inc. The first cell phone with
Android operating system that sold was in October 2008.
Android, to difference to others operating systems, it’s develop with open
Source and the people could modify your code for personalize or improve.
Initially, Android was an operating system that was used with mouse and
keyboard (operating system of PC) and your code was completely free or open
source. These characteristics changed when Google bought the company and it
sold your first device with this operating system.

4. Format:
The second draft will exhibit with Slides in power point or prezi; this will contain the
topic theory but with more graphics. Likely, I will present a video about the history of
mobile development.
