How can you stop the creaking noise created by the plastic hinge of your flip cell phone?

talcum powder quietens creaky floorboards so it might just help with the hinge of your mobile phone. Please do not put talcum powder on your phone. By placing talcum powder on the phone, you will cause the warranty to be null and void. I used silicone spray lubricant on the hinge and it worked great. Obviously you have to be extremely careful not to get it on any other parts of phone or inside the phone. I used a "Q-tip" saturated with the silicone, and applied to the hinge, as I worked the hinge back and forth until the squeak was gone. Then I wiped off the excess. I thought it might affect the plastic, but it did not.

If a man tells you he is separated with children and you have never been to his home or met his children and when he is not with you he turns his phone off what does this mean?

It means your sleeping with a married man. And most likely his wife doesn't know anything about you. GET WISE! Amen.

He could be hiding something from you or hiding you from his family. See if he says he is going somewhere with them or doing a specific thing and check it out. Ask him point blank what the deal is with not going to his home meeting his kids and the phone issue. I know he may think, if he is being honest, that it is easier for him not to involve you but that should be your choice, again, if he is telling the truth.

Can a cigarette lighter power inverter run a battery down when the car is off with a cell phone charger attached but not connected to the phone?

Saving A Car BatteryYes it can. Especially cell phone chargers. If your battery is already weak it is best to turn off the radio, A/C, interior lights etc. when turning off your car. If your alternator ever starts to go out on you while driving turn off anything that may pull from it, except the engine of course, and it will give you a little more time to get off the road or to the nearest gas station before going out completely.

It actually depends on the car. Some cigarete lighters are wire to the fuse panel (these will drain when car is off) and some are wired to the ignition switch (these will only drain when the car's ignition is on).

Which are compatible Bluetooth cell phones for 2007 Mitsubishi Outlander?

Answer 1: I have used several different phones, even some not listed on the official site, and most will work great.

Answer 2: Applies to 2007 Outlander XLS: Motorola RIZR is not fully compatible. It needs to be manually connected each time, and other registered Bluetooth phones will supersede it regardless of how how it is set up. I have been very successful with several Blackberrys, Siemens (Euro crosstype) phones, Motorola RAZR, Motorola SLVR, HTC Dash/Excalibur, and New HTC G1 (T-Mobile Google Phone).

What is over the horizon communication?

Most communications are conducted via electromagnetic radiation. This isn't universally true; there are submarine-to-ship comm systems that use high-frequency sound waves, but this is generally true. At lower frequencies, electromagnetic waves can be "ducted" around the curve of the Earth by being reflected from the ionosphere, or refracted by several atmospheric layers, providing over-the-horizon radio signals that follow the curvature of the Earth. Commercial AM radio and the paradoxically named "high frequency" amateur radio fall into this category.

Higher frequencies - above about 50 MHz - generally are line-of-sight. The signals do not follow the curve of the Earth, and don't reflect off the ionosphere; the signals travel straight off into space. Commercial television in the VHF range starts at about 54MHz, and commercial "FM" radio starts at about 87MHz; these signals are only receivable if you have a straight shot to the transmitter.

We can communicate "over the horizon" by using repeaters; stations that receive on one frequency and broadcast the same signal - "repeating" it - at a different frequency. Many repeaters are positioned on high towers, high buildings, or high mountains to provide broad area coverage.

But if you could put your repeater in space - at a 23,000 mile synchronous orbit - you could receive the signal in about 40% of the Earth's surface at once. Science writer and SF author Arthur C. Clarke proposed a scheme in which three such satellites, located 120 degrees apart around the globe, could provide coverage of nearly the entire world outside of the polar regions. (You can thank Clarke's shortsightedness for the low cost of your satellite TV service; it didn't occur to Clarke to patent the idea, and since it had been published openly, nobody else could patent it either!)

How do you understand texting?

The best way to understand texting is to first know how to text. If your cellphone has a keyboard like that of a computer, it is simple to put words and phrases together. If your cellphone is a flip phone and only has numbers, you will text based on the letters a specific number represents. For example, the number two on a flip phone represents the letters A, B, and C. when in a text format, if you press the number 2 twice, you will be left with the letter B. To spell the word "CAT" press the number 2 three times, the number 2 again once, and the number 8 once. Once you learn how to text, understanding messages becomes simple. If what confuses you is abbreviations, here are few common examples: "gtg" means got to go. "ttyl" means talk to you later. "btw" means by the way. "pos" means parent over shoulder. "brb" means I'll be right back. "w/" means with or "w/o" without...and so on. Sometimes people create their own abbreviations, which can make texting more confusing. Another common theme of texting is the addition of "faces" in a message. Here are some examples of faces" :) is a "smiley face." :( is a "frowney face." ;) is a "wink face." >:( is an "angry face." and so on.
