Greetings, I have been searching for a while (and couldn't find the answer) what is the touch resolution in the IPhone 4. When I say "touch resolution" I don't mean resolution of the touch screen, but the touch itself. F.e if I have a finger in a size of a needle, will I still be able to use the IPhone 4 touch screen? What is the resolution in which the iPhone will be able to sense my touch? An answer will be much appreciated, or even a guidance to where I should ask this question and get a good answer. Thanks in advance!
