Why Is Bluetooth Called Bluetooth?
When two devices need to talk to each other, they need to have a handshake on various parameters before the conversation starts. The first agreement is on the medium – will they use wires, or talk over some wireless signal?
Bluetooth is one such wireless signal (protocol) over which two (or more) devices communicate over.
Strange name though isn’t it – are the bluetooth waves invisible but blue and shaped like teeth? Wrong!
There is absolutely no relation between the name and the meaning.
The Bluetooth protocol was created by Ericsson (pre-Sony Ericsson) which is a major Swedish telecommunicati on company. They named it after the Danish viking king, Harald Blåtand. As legend goes, Blåtandhad the blessed ability to bring people negotiate with each other, and cometo talking terms.So skilled was he, that he was able to unite Denmark and Norway together! The literal translation of Blåtand means blue-tooth, hence the name Bluetooth for the protocol. It does precisely what Blåtand did – lets two wireless device to communicate with each other!
The Bluetooth symbol has HaraldBlåtand’s initials inscribed into it (in Runic).The two lines sticking out of the back of the B actually represent a Runic H – thats H for Harald .The B for Bluetooth also stands for Blåtand!

Tips to reduce the risk of exposure to cancerous electro-magnetic rays
If you are worried about recent revelations about cell phone radiation by the WHO, do not despair. There are a number of ways in which you can safeguard yourself to to a large extent.
According to well-known American non-government organization Environmental Working Group, or EWS, cellphone users can follow these tips to reduce the risk of exposure to cancerous electro-magnetic rays that cellphones may be emitting.
Always try to look up buyers' guide or Internet, or seek experts' advise to know about the radiation levels of your phone, or the model you intend to buy.
Most phones' model numbers are printed under the battery. Consider replacing your phone with one that emits the lowest radiation possible and still meets your communication needs.

Most phones' model numbers are printed under the battery. Consider replacing your phone with one that emits the lowest radiation possible and still meets your communication needs.
Fewer signal bars on your phone means that it emits much higher radiation to get the signal to the tower. Make and take calls when your phone has a strong signal, instead of incessantly using it and cursing your mobile operator.
Remember, it is your brain that will be getting fried due to poor signal!
Radiation shields such as antenna caps or keypad covers reduce the connection quality and force the phone to transmit at a much higher power with higher radiation. So while they may be protecting your phone, it is at the cost of your own health.
Limit children's phone use
Young children's brains absorb twice as much cell phone radiation as those of adults. Along with health agencies in at least 6 countries, EWG has recommended parents to set up limits for children's cell phone use, such as for emergency situations only.
They may be encouraged to either make short, sweet conversations, or use the good, old landline phones.
Cellphones emit maximum radiation when you talk or text, but not when you're receiving messages or listening. Hence, the age-old saying of listening more and talking less can come in handy here in reducing your exposure level.
Hold the phone away from your torso when you're talking (with headset or speaker), not against your ear, in a pocket, or on your belt where soft body tissues continuously absorb radiation.
Even while sleeping, avoid keeping it under the pillow or next to you. It should ideally be kept a few feet away even if you want to keep it handy just in case the President or the Prime Minister decide to call upon you in the dead of night.
Choose texting over talking
Phones use less power (and hence less radiation) to send out text than voice communication. And unlike when you speak with the phone placed next to your ear, texting keeps radiation away from your head.

Nokia unveils new dual-SIM phones
Nokia unveiled two new dual-SIM phones at an event called "Twins Day Out" here. While Nokia C2-00 is targeted at customers who want to access internet on the move, Nokia X1-01 is a music phone. Nokia had brought together 60 twins for the event and held a parade before showing its new handsets.
Dual-SIM phones are very popular in India at the entry-level and many industry insiders believe that it is Nokia's inability to come with such devices earlier that has hit the company hard.
It had brought one dual-SIM phone to Indian market last year. But by that time companies like Micromax and Spice had already established themselves in the market of dual-SIM phones.
"Nokia believes in being closer to the consumers and we want to develop products that meet the Indian consumer's changing needs and aspirations. We are sure Nokia C2-00 and Nokia X1-01 will set new benchmarks in the mobile internet and music space in the entry-level dual-SIM category," said Vipul Sabharwal, sales director at Nokia India.
Nokia claims C2-00 is the first dual-SIM phone to have 'easy swap', which offers consumers the convenience of changing SIM cards without the need to turn off the phone or remove the battery. The phone also remembers the settings for up to five separate SIM cards. Nokia said C2-00 will be available for around Rs 3,000.
Nokia X1-01, meanwhile, comes with a 'jumbo' battery that delivers up to 36 hours of continued music playback. It has in-built speakers and supports a memory card up to 16GB. This phone will be sold for around Rs 2,000.
