Ever experience that weird noise coming through your car speakers right before your cell phone is going to ring? (your cell phone needs to be resting close to the radio console) What causes that?

Also, I sleep with my cell phone right above my head, and I’ve noticed that I always wake up seconds before my phone rings. This happens to me constantly and at all different times. Do cell phones trasmit some kind of radiation or electromagnetic waves just before a call comes through and is that what’s waking me? Is it normal for "it" to be causing me to wake like that?

You read about all the magnetic waves that cell phones radiate, and how it is bad for your body (especially your brain.) But what are the worst case scenarios for using a cell phone for a long period of time? Do you get cancer? Less intelligent?

Also, is it true that the lower the battery of the cell phone, the more radiation it emits?

One final question, is it harmful to keep your cell phone next to your testicles/penis (scientific terms I’m using)?

Thanks.
