Can you paint your cell phone?
Yes! Everyone should paint phones with acrylic paint! Remember: NEVER USE WATERCOLOR PAINT! It will not last! Acrylic paint will not leave behind any stains or marks. Personally, (without revealing my name) I would recommend using bright neon, shiny or glow-in-the-dark paint. Feel free to add your own flare or style, for example: zebra or leopard print, stripes or polka-dots and lastly, you could perhaps, paint your own picture. Like a forest, beach, next-door neighbor, or even possibly, the Mona Lisa, if you feel to do so. Just believe in yourself and you can truly paint a masterpiece!!!
Contrary to popular belief, Canada is technologically on par with the US. In some cases they are even more advanced. Of course they have cell phones.
Directly, no. But a similar syndrome to Arthritiscalled Carpel Tunnel can result from too much repetitive motion (in your wrists) if your hands are not correctly positioned when entering text or holding your cell phone for long durations. Carpel Tunnel also affects typists who spend long hours at the keyboard entering data into a computer.
The causes of arthritis to date are unknown and the use of the joints will not cause arthritis. However if there is a predisposition to one of the many forms of arthritis in a person then they are likely to start noticing it eventually in the most used joints. Carpel tunnel is often related with Rheumatoid arthritis as this is a disorder that is the result of inflammation putting pressure on the metacarpal nerve in the top of the hand near the wrist.
How do cell phone jammers work?
How Cell Phone Jammers work
Cell phones are everywhere these days. According to the Cellular Telecommunications and Internet Association, almost 195 million people in the United States had cell-phone service in October 2005. And cell phones are even more ubiquitous in Europe.
It's great to be able to call anyone at anytime. Unfortunately, restaurants, movie theaters, concerts, shopping malls and churches all suffer from the spread of cell phones because not all cell-phone users know when to stop talking. Who hasn't seethed through one side of a conversation about an incredibly personal situation as the talker shares intimate details with his friend as well as everyone else in the area?
While most of us just grumble and move on, some people are actually going to extremes to retaliate. Cell phones are basically handheld two-way radios. And like any radio, the signal can be disrupted, or jammed.
In this article, you'll see how cell-phone jammers work and learn about the legality of their use.
Disrupting a cell phone is the same as jamming any other type of radio communication. A cell phone works by communicating with its service network through a cell tower or base station. Cell towers divide a city into small areas, or cells. As a cell-phone user drives down the street, the signal is handed from tower to tower.
A jamming device transmits on the same radio frequencies as the cell phone, disrupting the communication between the phone and the cell-phone base station in the tower.
It's a called a denial-of-service attack. The jammer denies service of the radio spectrum to the cell-phone users within range of the jamming device.
amming devices overpower the cell phone by transmitting a signal on the same frequency and at a high enough power that the two signals collide and cancel each other out. Cell phones are designed to add power if they experience low-level interference, so the jammer must recognize and match the power increase from the phone.
Cell phones are full-duplex devices, which means they use two separate frequencies, one for talking and one for listening simultaneously. Some jammers block only one of the frequencies used by cell phones, which has the effect of blocking both. The phone is tricked into thinking there is no service because it can receive only one of the frequencies.
Less complex devices block only one group of frequencies, while sophisticated jammers can block several types of networks at once to head off dual-mode or tri-mode phones that automatically switch among different network types to find an open signal. Some of the high-end devices block all frequencies at once, and others can be tuned to specific frequencies.
To jam a cell phone, all you need is a device that broadcasts on the correct frequencies. Although different cellular systems process signals differently, all cell-phone networks use radio signals that can be interrupted. GSM, used in digital cellular and PCS-based systems, operates in the 900-MHz and 1800-MHz bands in Europe and Asia and in the 1900-MHz (sometimes referred to as 1.9-GHz) band in the United States. Jammers can broadcast on any frequency and are effective against AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN and Nextel systems. Old-fashioned analog cell phones and today's digital devices are equally susceptible to jamming.
The actual range of the jammer depends on its power and the local environment, which may include hills or walls of a building that block the jamming signal. Low-powered jammers block calls in a range of about 30 feet (9 m). Higher-powered units create a cell-free zone as large as a football field. Units used by law enforcement can shut down service up to 1 mile (1.6 km) from the device.
Electronically speaking, cell-phone jammers are very basic devices. The simplest just have an on/off switch and a light that indicates it's on. More complex devices have switches to activate jamming at different frequencies. Components of a jammer include:
Antenna
Every jamming device has an antenna to send the signal. Some are contained within an electrical cabinet. On stronger devices, antennas are external to provide longer range and may be tuned for individual frequencies.
Circuitry
The main electronic components of a jammer are:
* Voltage-controlled oscillator - Generates the radio signal that will interfere with the cell phone signal
* Tuning circuit - Controls the frequency at which the jammer broadcasts its signal by sending a particular voltage to the oscillator
* Noise generator - Produces random electronic output in a specified frequency range to jam the cell-phone network signal (part of the tuning circuit)
* RF amplification (gain stage) - Boosts the power of the radio frequency output to high enough levels to jam a signal
Power supply
Smaller cell phone jammers are battery operated. Some look like cell phone and use cell-phone batteries. Stronger devices can be plugged into a standard outlet or wired into a vehicle's electrical system.
Do Mady and Cara Gosselin have cell phones?
According to Kate Gosselin, both Mady and Cara have hand-me down iPhones from their mother.
If you go to Kate's website, Kate Plus my 8, and click on questions and answers (Q&A) and read some then it's obivious they have one, although they have thousands of rules about it (they are listed on the site) and there is no telling what their number is, besides, that is one of the rules, 'no answering unknown calls/texts' and, if they do answer, Kate looks at their cell and reads the messages and has this code so she can read it whenever and there is another rule going along with that: 'No deleting meassages' she can somehow tell if they deleted one.
A link to the website is under Related Links.
What is meaning of cell phone error pps 6180?
This is an automated message from some cell phone providers such as AT&T, Cingular and several others that lets the caller know that the number they are trying to reach is either out of service range (in an area without coverage), disconnected, or temporarily unreachable for another reason.
If you're sure you're dialing the right number and you know the person hasn't changed their number, try calling back at a later time.

How do you watch Disney channel on your cell phone?
There are several ways, but the one I use is the simplest.
Go to Wikipedia and find out what the episode you want to see is called and then search it on youtube. Before watching, make sure the user you selected has all 3-4 parts, otherwise it is tedious trying to find the next part right after something exciting, dramatic, or funny has happened.
There is the rare case where no one on youtube has posted the episode, which is annoying, but rare.
How do you call cell phone to cell phone US to New Zealand?
Your call will be almost like your typical international phone call, however a cell phone is slightly different. You will first need to dial the "+" symbol into the number.

Why did Henry T. Sampson make the cellular phone?
According to http://inventors.about.com/library/weekly/aa070899.htm the inventors of the Radio telephone system, the modern cell phone, was a man named Dr. Martin Cooper. Other inventors include, Richard W. Dronsuth, Albert J. Mikulski, Charles N. Lynk Jr. James J. Mikulski, John F. Mitchell, Roy A. Richardson, and John H. Sangster. Cooper made the first call on a portable cell phone in April 1973. He made that call to his rival, Joel Engel. Bell Laboratories introduced the idea of cellular communications in 1947 with the police car technology. Motorola was the first to incorporate the technology into portable device that was designed for use outside of a automobile.

-----------------------------------------------------------
Henry Thomas Sampson, Jr. (born in Jackson, Mississippi in 1934) is an American inventor.
He graduated from high school in 1951 from Lanier High School in Jackson, Mississippi. He then attended Morehouse College for a couple of years before transferring to Purdue University. He received a Bachelor's degree in science from Purdue University in 1956. He graduated with an MS degree in engineering from the University of California in 1961. Sampson also received his MS in Nuclear Engineering from the University of Illinois Urbana-Champaign in 1965, and his PhD in 1967.
He is the first African American to earn a Ph.D.in Nuclear Engineering in the United States. Some of his accomplishments include being a member of the United States Navy between the years 1962 and 1964 and earning an Atomic Energy Commission honor between 1964 and 1967. Later he was awarded the Black Image Award from Aerospace Corporation in 1982. He was awarded the Blacks in Engineering, Applied Science Award, and prize for education, by the Los Angeles Council of Black Professional Engineers in 1983. In June 2007, Sampson was married to Laura Howzell Young in St. Thomas, U.S. Virgin Islands. Young-Sampson is a professor in the College of Education at California State University San Bernardino.
Sampson was employed as a research chemical engineer at the U.S. Naval Weapons Center, China Lake, California, in the area of high energy solid propellants and case bonding materials for solid rocket motors. Sampson also served as the Director of Mission Development and Operations of the Space Test Program at the Aerospace Corporation in El Segundo, California.
His patents included a binder system for propellants and explosives and a case bonding system for cast composite propellants. Both inventions are related to solid rocket motors. He received a patent, with George H. Miley, for a gamma-electrical cell on July 6, 1971.
On July 6, 1971, Sampson was awarded a patent for the "gamma-electric cell". The gamma-electric cell is a device that produces a high voltage from radiation sources, primarily gamma radiation, with proposed goals of generating auxiliary power from the shielding of a nuclear reactor. Additionally, the patent cites the cell's function as a detector with self power and construction cost advantages over previous detectors.
Who invented the first mobile phone in the world?
Doctor Martin Cooper invented the modern cell phone. He invented the technology responsible for the cell phone when he was the Director of Research and Development at Motorola. Dr. Martin Cooper is also known as the first person to make a call on a cell phone. His revolutionary call took place in April of 1973 in New York. He is currently the CEO of an antenna corporation.
When was the 1st mobile phone invented?
According to historical records, the first mobile phone was invented by Ericsson in Sweden in the year 1956. The device came to be known as the Mobile Telephone System. The phonewas easy to use since it was automatic but its biggest downside was that it weighed about 40 kilograms. Later in 1965, an upgraded version was launched by the company in order to convince the consumers which became very successful between 1965 to1983 since many bought it as it was only 9 kilograms. Leonid Kupriyanovich, a radio engineer in Moscow, Russia developed an automatic mobile phone known as LK-1 in 1957. A year after, Russia also developed and introduced Altay service, which could be used by mobile phone users while driving. Russians continued to use the service until 1970.
How is truth or dare played while texting?
Ask your crusha question in a flirting way, Then ask if he or she wants to play truth or dare.
Your husband tapped your phone is it illegal?
Whether or not tapping someone's phone is illegal depends on the state in which you and your husband live. If the state you reside in is a one party state then no it is not illegal. One party state means that as long as one party is aware that the phone conversation is being recorded then it is legal.
How do you get your parents to give you a cell phone?
you don't. you think about whether you really need one, why you want one. then if you think of a very good reason why you shoud have one, you ask your parents if they are okay with it as long as you are responsible with it. you may come to an agreement that it is a good idea to have one if you buy it or legitimately earn it yourself. if your parents say no, accept it and trust their wisdom. besides, I'm willing to bet they grew up without a cell phone and lived through it.
you asked.
Is texting someone else cheating?
I think it's up to what kind of texting the person is sending to the other person. We will never know unless we saw the text and read them. So I think it's better if you ask this person so that way, what ever comes out will not be such a big issue, agree?
How long do you wait before texting a girl back?
Of course
If you like the guy don't answer right. Away and even if you didnt
But if you like him just try take the same time as him
But obviously if he takes 5 hours to reply you won't do the same cuz maybe the do was doin something and couldn't reply don't take it personal the duded has a life too
But iF he takes a lot to reply just replay back in like 15 or 20 minutes
Hope this helps
