I have strange sensation when I hold my iPhone 3G too long and I even have strange orange traces on the hand were my skin touch the iPhone as if the phone burned my skin ... is it normal ?
why don't you do a test of holding the floor sample iPhones wherever you purchased your iPhone, to see if you have the same sensation on your hand ? just to see if it is just the one you have or all that your hand feels that burning sensation with. if the floor samples do not have the same effect, maybe you can ask for a replacement? but if they all do, maybe it is some time of allergic reaction - although, I am no doctor . . .
Well i do not know but i land mine to my father for a few minutes. He was playing a game and after a while he had the same tingling in the hand than i feel.
But can it comes from the phone ? Is it normal to feel little tingling in the hand?
If you hold something tight for too long, nerves can be squeezed and cause tingling. Orange stains on the hand can be caused by smoking. For causes of unexplained burns to the hand, see:
