Symbian OS C++ for Mobile Phones Volume 3 draws on the experience of Symbian’s own engineers to provide a thorough grounding in writing C++ applications for mobile phones that use Symbian OS version 9.0 and beyond. It won’t teach youeverything you need to know about developing Symbian OS applications – no single book could do that. However, it will take you a long way along the road to being an effective Symbian
OS developer, and give you a deep understanding of the fundamental principles upon which Symbian OS is based...
The age of information and technology has brought mankind lots of the
“breakthrough” inventions, in which the appearances of mobile phones with the cheap
costs and high application has made the great changes for people’s lives, especially for
the youth. Most of the cities- dwellers possess one or more hand phones, in particular,
the secondary and college students do.
I’d love to say that this book is for you, no matter who you are. But no one book
could cover the wide range of cell phone users when it comes to discussing a
new system. So, how do you know if this book is for you?
Maybe all you’ve ever used a standard mobile phone for is making phone calls.
Maybe you occasionally send a text message or use your cell phone camera to
share pictures with friends.Maybe you’d like to jump ahead to the latest phone
software, but you feel a little nervous about that....
With some six billion mobile subscriptions now in use worldwide, around three-quarters of the world’s inhabitants now have access to a mobile phone. Mobiles are arguably the most ubiquitous modern technology in some developing countries, more people have access to a mobile phone than to clean water, a bank account or even electricity. Mobile communications now offer major opportunities to advance human development from providing basic access to education or health information to making cash payments and stimulating citizen involvement in democratic processes.
For some years, commentators have been predicting the 'convergence' of the Internet and
mobile industries. But what does convergence mean? Is it just about mobile phones providing
Internet access? Will the coming together of two huge industries actually be much more about
collision than convergence? In truth, there are lots of possibilities about what convergence
might mean, such as:
• Internet providers also supply mobile phones - or vice versa, of course.
• The user's mobile phone is replaced with a palmtop computer.
• The mobile Internet leads to a whole range of new applications.
The third generation (3G) mobile communication system is the next big thing in the world of mobile telecommunications. The first generation included analog mobile phones [e.g., Total Access Communications Systems (TACS), Nordic Mobile Telephone (NMT), and Advanced Mobile Phone Service (AMPS)], and the second generation (2G) included digital mobile phones [e.g., global system for mobile communications (GSM), personal digital cellular (PDC), and digital AMPS (D-AMPS)].

A mobile phone is a Swiss Army knife. It is not a chef’s knife or a buck
knife. We keep wanting new features on the phone, like texting, voice
memos, browsing, a camera, music, and television, because we would
like these things in our pocket and the phone is already there.
When Evan Williams, founder of Blogger and Odeo, had to pick up what he would
do next to revolutionize the Web, he decided to go mobile. Evan returned the VC
money to focus on Twitter—a service that allows keeping in touch with friends via
alerts to and from your mobile phone (and instant messenger and web)! After six
months of launch, Twitter had reached 50,000 active users. The number doubled to
100,000 in just one month after Twitter won the Best Blog award at South By South
The mobile phone is by far the most widely available device with rendering capabilities
in the world, and it is very likely that this will continue to be the case. However, this
ubiquitous tool may not continue to be centered around its phone function for much
longer, as it evolves more and more into a multifaceted device, which you might want to
call a mobile Gizmo (see Bruce Sterling’s keynote at SIGGRAPH2004). Inevitably, graphics
is becoming a core part of such a Gizmo.
Mobile phones are convenient and frequently invaluable, yet exposure to their
electromagnetic radiation is invisible. Therefore, any danger this exposure poses
may be easily dismissed.
• Exposure is long-term and its effects on the body, particularly its electrical
organ, the brain, are compounded by numerous other simultaneous long-term
exposures including continuous waves from radio and TV transmitter towers,
cordless phone base stations, power lines, and wireless/WiFi computing devices....

In recent years, possible health hazards due to radiofrequency radiation
(RFR) emitted by mobile phones have been investigated. Because several
publications have suggested that RFR is stressful, we explored the potential
biological effects of Global System for Mobile phone communication at
900 MHz (GSM-900) exposure on cultures of isolated human skin cells
and human reconstructed epidermis (hRE) using human keratinocytes.
