Frequently Asked Questions (FAQ) for Cellular Phones

A handheld computing device has an operating system (OS), and can run various types of application software, known asapps. Most handheld devices can also be equipped with Wi-Fi, Bluetooth, and GPS capabilities that can allow connections to the Internet and other Bluetooth-capable devices, such as an automobile or a microphone headset. A camera or media player feature for video or music files can also be typically found on these devices along with a stable battery power source such as a lithium battery. Increasingly mobile devices also contain sensors like accelerometer, compass/magnetometer andgyroscope allowing detection of orientation and motion.nHandheld devices have become ruggedized for use in mobile field management. Uses include digitizing notes, sending and receiving invoices, asset management, recording signatures, managing parts, and scanning barcodes. nRecent developments in mobile collaboration systems employ handheld devices that combine video, audio and on-screen drawing capabilities to enable multi-partyconferencing in real-time, independent of location.nHandheld computers are available in a variety of form factors, including smartphones on the low end, handheld PDAs, Ultra-Mobile PCs and Tablet PCs (Palm OS,WebOS)nUsers can watch television through Internet on mobile devices. Mobile television receivers have existed since the 1960s, and in the 21st century mobile phone providers began making television available on cellular phones. nNowadays, mobile devices can create, sync, and share everything we want despite of distance or specifications of mobile devices. In the medical field, mobile devices are quickly becoming essential tools for accessing clinical information such as drugs, treatment, even medical calculation.nDue to the popularity of Candy Crush and other mobile device games, online casinos are also offering casino games on mobile devices. The casino games are available on iPhone, Android, Windows Phone and also on the iPad. Available games are roulette, blackjack and several different types of slots. Most casinos have a play for free option. nIn the military field, mobile devices have created new opportunities for the Army to deliver training and educational materials to soldiers around the world.nSource for a2a...What are the advantages of using mobile handheld devices? What are the disadvantages?

Thanks for A2AnIn my opinion, those crimes should be investigated and the guilty parties should be brought to justice - whether they are Jews or Arabs. As I already wrote on the subject, while it's extremely flattering to the public ego, that Jews were able to enter an Arab village in the middle of the night, to commit arson and to leave without anyone being the wiser - it's also extremely unlikely. There are dogs in the villages and most of them are outside pets. And none barked? Read Sherlock Holmes "The Adventure of Silver Blaze". They barked, but the frightened villagers (who think that they got "tagged" for throwing stones) were too afraid to go out & check? Forgive my French: Bullshit. This is what happens to Jews in the enemy village/city: 2000 Ramallah lynchingnI am not saying that it's impossible, that Jews did it. We have our own crazies. After all, there were these guys: Jewish UndergroundnBut, as I said, in the unlikely case, that these are Jews, I demand that the conditions of their punishment/imprisonment would be identical to those of Arab terrorists:nPA is paying to rebuild the houses of families of Arab terrorists that Israel demolishes. While demolishing Jewish home would not help in the prevention (collective-oriented Arab society vs individual-oriented Jewish one), something drastic *should* be done. I suggest that the government would confiscate the house and'd pay for the new house built outside of Judea & Samaria. nWhile in jail, the Jewish terrorists should have free education, free medical care and visits from the families (conjugal visits included). Internet access, special foods and cellular phones - comes without saying. nWhen Arab terrorists'd be released as a concession, because of Ramadan or in exchange of Jewish soldier captured by an Arab terrorist group, so'd some of the Jewish terrorists be released - one Jew to ten Arabs sound fair enough. Like Arab terrorists, the Jewish terrorists should sign a document of promise never to repeat terrorist activities after which, unless they'd break their promise, any discrimination against them would be illegal.What do you guys think should be done about Price Tag Attacks?

Technology is based on our continued understanding of nature and the discovery of new scientific principles, which can be applied to help enhance and extend our lives. All technology has a purpose. Generally, the ultimate uses for specific technologies is virtually impossible to predict. Let me provide some examples. The airplane had both a commercial and military use from its beginning. While nuclear energy was specifically developed for a wartime purpose, it has enjoyed more usage in the commercial electric power generation sector. Integrated Circuits were initially used in missile guidance and military computer systems and now have widespread usage in both commercial and military systems. Microwaves radiation was developed to enhance the resolution of Radar, and while it continues to serve that purpose it is widely used in microwave ovens. GPS was developed for battlefield positioning and again while it is used in highly accurate munitions, it has also found widespread usage in cheap commercial navigation systems and cellular phones. Electromagnetic technologies are widely used in both military and commercial wireless systems. However, their use in electromagnetic weapons threaten some of society's most important infrastructure elements (for example the electrical grid). Likewise, information technologies have become pervasive in our increasingly complex and interconnected infrastructure, but their use in cyber weapons threaten that very infrastructure. Breakthroughs in biological technologies could lead to more effective cures of genetic diseases and the possibility for extending life. However, their potential use in biological weapons could spread unknown strains of highly contagious diseases. I would say just about every technology I can imagine has the potential for both constructive and destructive purposes. The challenge in some of the newer biological/information technologies is the potential for their malicious "viral" spreading in ways unimaginable by their creators. A good book on the evolution of technology is Brian Arthur's, The Nature of Technology: What It Is and How it Evolves. One of the interesting observations (actually he states it as a general rule) Arthur makes is "every technology contains the seeds of a problem, often

I saw Frank Abagnale on this list and was very satisfied with that answer as Frank was one of the first pioneers in Social Engineering, even before the invention of the modern home PC. One might argue though that the smartest criminal was the guy that followed in Franks footsteps and became a legend among hackers. That man is no other than.Kevin Mitnick.I mean after all, this is his business card (later in life after released from prison)At age 13, Mitnick used social engineering and dumpster diving to bypass the punch card system used in the Los Angeles bus system. After he convinced a bus driver to tell him where he could buy his own ticket punch for "a school project", he was able to ride any bus in the greater LA area using unused transfer slips he found in a dumpster next to the bus company garage. Social engineering later became his primary method of obtaining information, including usernames and passwords and modem phone numbers.Mitnick first gained unauthorized access to a computer network in 1979, at 16, when a friend gave him the phone number for the Ark, the computer system Digital Equipment Corporation (DEC) used for developing their RSTS/E operating system software. He broke into DEC's computer network and copied their software, a crime for which he was charged and convicted in 1988. He was sentenced to 12 months in prison followed by three years of supervised release. Near the end of his supervised release, Mitnick hacked into Pacific Bell voice mail computers. After a warrant was issued for his arrest, Mitnick fled, becoming a fugitive for two and a half years.According to the U.S. Department of Justice, Mitnick gained unauthorized access to dozens of computer networks while he was a fugitive. He used cloned cellular phones to hide his location and, among other things, copied valuable proprietary software from some of the country's largest cellular telephone and computer companies. Mitnick also intercepted and stole computer passwords, altered computer networks, and broke into and read private e-mails

This is a tough issue that I'm not sure anyone has really solved yet, but here are my thoughts for your 3 solutions.Yes this might be a bit personal or creepy but I feel like it's becoming less so since people are actually using their phones less and less. You'll want to be clear that you're not selling their phone number to a marketing agency or they won't be receiving any solicitations. Also for this to be effective, you will have to verify that this is in fact their phone number meaning a text message confirm or something to that effect to prevent people from putting in some random phone numbers they don't own.The cons for this are pretty big issues so I wouldn't recommend this. What I might recommend for this is to use the IP address private email domains to alert you to suspicions of a multiple accounts in which you can investigate. Obviously working with the threshold of this would be useful.CC number is complicated... you generally do NOT want to be storing CC numbers since it creates a huge liability for the company. As such you normally use some sort of service which provides a token, and suddenly thing become very complicated. Unless you need to set this up anyways for payment of your service, this can be a lot of work. That being said, CC is not a bad idea if you really want to only have people who are a bit more committed to your product to actually go and give it a try. Also to increase comfort levels, you can potentially not ask the for their CCV (i'm not sure if this will screw up validating the authenticity of the numbers).

I honestly don't feel that having just email will cause absurd amount of freeloaders to continuously use trials. Also someone who's doing that will most likely never buy your service anyways (or is not the kind of customer you want), however without knowing what your service is exactly it's hard to say. Out of the 3 you have here I probably recommend phone number.
