Do you not realize that the iPhone uses the same bands as most every other quad-band GSM phone? Do you not realize that Apple is not the only company to use the same technologies?
Correlation is not causation. The very fact that you use that sort of logic makes me skeptical of your claims.
I got some bad news for you -- your Samsung is going to "bathe your brain" in the exact same types of radiation as the iPhone did.
That said, I fully expect that getting a Samsung phone will alleviate the problem. You know why? Because you've already decided that the iPhone has caused various sensations which are almost certainly psychosomatic in nature. You've already told yourself what the problem is, and thus as soon as you change phones you will notice that the problem's gone; getting a new phone will (in your mind) vindicate you, and the disappearance of your symptoms will confirm your initial diagnosis.
Sad thing is, there's no way I can convince you otherwise. I fully believe that you feel the sensations you describe. I don't think they're a result of the iPhone's radio emissions though -- but since that's what you've ascribed them to it's going to be damn difficult for anyone to convince you otherwise.
Can I at least have your iPhone? I mean, since it's a harmful device you wouldn't mind giving it to some
disbelieving **** like myself, right?
