I actually had a bubble boy (little bro of one of my Jr bridesmiads who was very disapointed he wasnt the ring bearer, but hes a little hellion and I didn't trust him on stage .so i gave him that job!)

How can texting while driving be a good thing?
Well, the short answer is that there are none. Texting distracts you from the road, even if you can look up and still type correctly you're attention is still focused on the cell phone not the road. Cell phone use is also illegal while driving in several states.
If you text at night the light from the cell phone can readjust your eyes and temporarily alter your night vision which you render you incapable of seeing something on or beside the road and result in an accident.

What are disposable cell phones?
While most prepaid cell phones are not disposable phones, most disposable cell phones are prepaid phones. Disposables have not really caught on in the U.S., since pretty decent prepaid phones can be purchased, on sale, for as little as $20 or even $10, while some disposables cost upward of $50. Prepaid carriers also offer advanced phone equipment that can cost over $100 and comes with a year warranty; such phones are hardly disposable. There are different concepts of disposable cell phones. The phone is often an unlocked phone usable with almost any carrier, but not necessarily. The instrument has very limited functionality: you can talk, and you can text. It might not have a display of any kind. It might come with minutes, or you may need to contact a prepaid carrier to purchase minutes. But the main idea is that the phone is ready to go, or just about; requires no contract or any kind of sign-up; and is cheap enough that you're comfortable tossing it after using it for just one vacation or even just one hour of talk. Some companies offer a small refund on phones returned for recycling. Because there is no record of a purchaser, disposable phones are suspect tools of terrorists, recent news articles state.

Why is copper in a mobile phone?
The main reason copper might be used in any electronic device is because it is one of several excellent conductors of electricity, and it is malleable - easily shaped as needed.
Durability is not really an issue in cell phones, as the conductors are not usually subject to stress due to motion (except to some extent with tilt &/or slider designs.) Copper is NOT unbreakable. Single, or even a couple, strands of most CAT 5 copper Ethernet cable (whether solid copper or stranded copper) can be broken with bare hands, and even heavier cables can be broker with adequate force.

Is it better to power off your tablet while charging it?
While your tablet is charging it is best to turn it off charging if you want it to charge quicker. Playing apps can take triple the time it should do to charge. If you do not need it charged fast have fun with it. It doesn't really matter if you've got lots of time :)
Why are people addicted to mobile phone?
People have developed a belief that they must be able to connect with anyone at any time about any stupid, unimportant thought that drifts through their consciousness. They've developed a phobia about missing a call or a text message; they no longer understand degrees of importance - they think every minuscule detail MUST immediately be shared. It's a tech induced neurosis.
AnswerSo true! Like those stupid phone commercials with Luke Wilson: "Ooooh, if you have Sprint you can't talk on the phone and surf the web on your phone at the same time! Oooooh, the horrors!" Who on earth needs to be able to talk on the phone while surfing the web on the phone? Couldn't you, maybe, CALL THE PERSON BACK IN FIVE MINUTES? Like your inane conversations with your friends are so important that they can't be interrupted for five minutes. "You can make reservations for sushi without ever leaving the conversation!" Great, except, why on earth would I NEED to make reservations for sushi without ever leaving the conversation?
I'm so sick and tired of phone companies trying to convince me that I NEED to have the absolute latest technology available.
Is it bad to leave your cell phone in when battery fully charged?
All rechargeable batteries such as cell phones, cordless phones, laptop computers, etc., need to be allowed to fully discharge and then recharge to full power to prevent them from acquiring a "memory". If they are always kept at full charge, then it will actually shorten the battery life, making the time between re-charging shorter.

When and who invented the cellphone?
The idea of cell phones began in the 1920's with police radios, but the first one was invented in 1948 by Bell Labs. The cell phone we know today was invented by Dr. Martin Cooper of Motorola in 1974 and was only used by government until 1984 when they were first sold to the public. The first cell phones were large, heavy, and expensive to use. Many were in a bag and looked like a house phone but the entire bottom was a battery.
Who invented the first "modern cell phone" as we know it? Dr.Martin Cooper ( director of R&D Motorola USA) is credited with "inventing" one in 1973 along with his research team, and funding from the US government. So the first cell phone company was technically Motorola USA although technological ground work laid by others, AT&T, Bell Labs, US military, etc. was obviously used to make it all work. Martin cooper was born in Chicago in 1928 and graduated from IIT in Electrical Engineering. In 1954 he was hired by the Motorola Company( that's in the USA).
The first "mobile phone" was in Sweden by Lars Magnus Ericsson (May 5, 1846 - December 17, 1926) A very common name in cell phones today.
The first cell phone was made by Bell labs in 1947, but Dr. Martin Cooper of Motorola is given the most credit for the invention of the cell phone in 1974. The first cell phones were only sold to the government and in 1984 they finally were offered to the public. They were large, heavy, and copied land line phones in style and were carried in a zippered bag with the battery taking up the whole bottom.
Martin Cooper ( inventor of the cell phone) added, "As I walked down the street while talking on the phone, sophisticated New Yorkers," ( in new york)" gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973, there weren't cordless telephones, let alone cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter - probably one of the more dangerous things I have ever done in my life." the phone call was made in new york on April 3, 1973.
The first fully automatic mobile phone system, called MTA, was developed by Ericsson and commercially released in Sweden in 1956.
This system had cells, but the phones could not move from one cell to the other without having to end the call.
In 1970, an engineer at AT&T's Bell Labs, an American company, invented a method to allow cell phones to move from one cell to another during a call; called a "call hand-off."
The first truly successful cellular network was the ARP, introduced in Finland in 1971. It is viewed as a 0G (zero G) network which had very good coverage and achieved great popularity.
All the phones used in the previously mentioned networks were large in size, not suitable for being held by hand. They were mostly applied in automobiles, with the main device installed in the trunk of the car, attached by wire to a handset near the driver seat.
The first practical hand-held cell phone was invented by Motorola, an American company, in 1973. Dr. Martin Cooper, an American born in Chicago, is the inventor listed on the US patent that was used to register that device.
Can mobile phones be infected with a virus?
In theory yes, but it would be difficult to design and distribute a virus for a mobile given that there are so many different kinds of phone systems. The chance of mobile infection is slim due to the sheer lack of viruses that have been deployed.
