There is no definite answer currently. Scientists and doctors will know more as the years progress, because cell phone waves would have a gradual effect on the brain, and evidence will become apparent (and more people eligible) to figure it out.
So, better safe than sorry... don't sleep with your cell phone by your head.
Put the name of Dr.Vini Khurana into Google and you will find some potentially useful and disturbing information about the safety of cell phones.
in my opinion 70% harmful..... LOL
Some research has concluded that cell phone signals can cause cancer and disruptions to the ecosystem. Actually that is incorrect. Cell phones work off of microwaves which are the second type of electromagnetic energy on the spectrum and are only harmful in great quantities like what is found in a microwave oven. Cell phones do not run on near that amount and are not harmful towards you nor the environment.
Cell phones do emit a type of non-ionizing radiation.
Phone radiation can be harmful to humans. It is harmful when the person is on the phone a lot.
The simple answer is no. First, Radio waves do absolutely nothing to your health. It is the electromagentic waves that come from the cell phone that "maybee" harmful to your health if you use your cell phone constantly. If you have a lead case around the cell phone it may help but you are better off buying a bluetooth headset which uses even less ectromagentic waves. The real key is to not let your cell phone get so hot, this means that more radiation from your battery and electronic parts are spreading - to your head if it is close to it. At the worst, a hot cell phone can harm human cell tissue, however, there are no known direct cases of any type of cancer from cell phones.

It's not harmful in any way. If you can put up with it, it won't hurt you.
When it comes to cell phone batteries, it is not the manufacturer that counts, but the type of battery. The battery should be made specifically for the brand of phone being used and it should be made of Lithium for longer life.
It's theoretically possible, but probably unlikely unless you're literally keeping them back to back. If you have the capability to keep your cell phone and your wallet in separate pockets, you will reduce the risk to virtually zero.
what is an unlocked cell phone
You will need another AT&T cell phone are a compatible GSM cell phone.
The Cell Membrane Protects The Cell Of Anything Harmful.
The cell membrane is what keeps harmful chemicas out of an animal cell. It regulates traffic of all chemicas and proteins in and out of the cell.
