Because having the antenna on the inside makes a difference? You do realize that the radio signal still penetrates the plastic and gives you the same dose of radiation?

It seems like it may be even worse to have direct physical contact with the Antenna now, no?
 
I like my doctors to be able to spell. It's a detail thing. Call me picky.
 
You should be happy. If a call is coming in you can just taste it. Or when something is interfering you can also taste it!

No the radiation has nothing to do with physical contact. Distance does play a role. But the amount of distance inside the case vs outside not significant. What apple has done here is make a larger antenna without increasing size. Which allows it to pick up on weaker signals. The transmitting power isn't changed, as that's limited by law. So the amount of power beamed out is the same. (which is the radiation you're exposed to at close range) The external antenna allows better pickup of a signal from a tower, ie how your car has it's antenna on the outside as metal and other things will weaken the incoming signal.

Thanks for the explanation.
Something is wrong with these things though.

My iPhone 2G, 3G and 3GS never made my fingers tingle or give me this weird "metal taste" in the mouth like my iPhone 4 does.

Creeps me out. Hopefully the free Bumper that's on the way helps out. I'm on "speakerphone" a lot right now. :)
 
I'd say a case would work, you can test though, just wrap it in something and hold it and see if you can feel it. Its prolly coming through the metal sides and possibly is the same resonance frequency as your tooth.
 
If you do a Google search on terms like "cell phone metallic taste", you'll find that some people do get a metallic taste when they're near certain cell phones and/or towers.

Haven't run across a good explanation yet, though.

PS. Agreed on the moderation. Each summer we get a ton of rude and ignorant posts, from people both new and old. Unfortunately the mods can't read every post, so the next best thing to do is click that little red triangle on rude or coarse posts and complain. Often that gets such a poster put into at least a timeout where they can't respond for a while.
 
Hey look on the bright side - it looks like you have an extra antenna in your mouth now! Is the reception problem fixed? :D

Get a metal crown. Stay Tuned.

I know this sounds like I weird title, but please give me a chance to explain. I have recently received my iphone 4 and love it, but there is a slight problem. I have a crown over one of my tooth's and for some reason when I touch the metal part of the phone (antenna), either holding in my hand, or gripping the side I get a awful taste in my mouth and my head hurts. I know your thinking this is stupid, but I wouldn't make this up.
Would a rubber case stop this from happening?

thanks

Sorry to hear all of the flaming in this thread. I am a neurophysiologist perhaps I have a few ideas that might help. First, when your skin touches the metal you are creating a circuit (a high impedance circuit, but a circuit nonetheless). Try positioning the phone the way you would when it causes the pain but interpose an insulator between your skin and the phone (plastic food wrap would do the trick). If it does not cause pain, then you know that the issue is that an electrical circuit is formed and probably a bumper, being a good insulator, would help. If it does not, then there is some sort of weird interaction based on the electromagnetic radiation, or a more mundane explanation.
 
some serious jerks in this thread—they seem to show up in bunches whenever anyone post something remotely related to the potential negative effects of RF.

To the original poster, you are most likely one of those people who is more sensitive to RF...
 
This forum desperately needs more moderators.

Yeah, but they are busy repairing their tinfoil hats right now.

As far as doctors and their spelling skills are concerned, with all due respect to proper spelling, I just want doctors who can tell LEFT from RIGHT while at the operating table.
 
If the iPhone 4 has issues with fillings or certain types (e.g. deteriorating) of fillings, that would be some baaaad press for Apple. Then again, if this is true, there should be other reports of this phenomenon popping up soon.
 
All kidding aside. It could be coincidence that you are having those symptoms. You just got your iP4 and you started having the symptoms.

I've had the symptoms. But it wasn't when using a cell phone. it would come and go. Mine was caused from root decay. I had to have a root canal done. My regular DDS couldn't see anything on x-rays. Sent me to a specialist. He found the problem behind my sinus.

You might want to visit your DDS.

So you're attending "metical" school?

Yet you don't know the difference between "your" and "you're"...

These are our future doctors :eek:
 
That sort of spelling and lack of attention to grammar is indeed an indicator of sloppy thinking. I, and everyone else, expect better from people in the professions. Spell like a 2nd grader? Well, it's going to be hard for you to get the respect you are going to need in your career.

F u wanna spel lik this, thenn done tel any1 u r a dr. <---Big piece of good advice here.

As for your problem with your teeth, why are you asking people on the Macrumors' forum? I think that if you talked to someone in the dental school they could give you a better answer than we could. You might even learn something. :)
 
You say you're going to medical school yet you come to a rumor forum to ask people about your phone/filling issue...... ffs please find another line of work. I've been a nurse going on 12 years and it sounds like you don't really have what it takes. Good luck.

You've been a nurse for 12 years, and yet, you still can't offer an explanation to what the OP is experiencing. All nurses do is wipe dirty a** and change diapers. You have no critical thinking or decision making skills. I write orders, you follow them.

To the OP, try using a case first to alleviate the problem. If that doesn't work, talk to your dentist to see if they can offer a better solution.
