Antennagate: how much of the phone's side should I not touch? Antennagate indicates that I should avoid touching that spot of the iPhone where the two metal pieces nearly touch each other - touching here would electrically bridge the two pieces and decrease antenna performance... but it's nearly impossible to hold the phone and not touch it there! So here's my question:

Question: Should I not touch the two metal parts simultaneously at all, or just not put a finger precisely over the gap? It is okay to touch one centimeter from both sides of the gap? Two centimeters? Half a centimeter?

If I were to just put a little bit of tape over this side, how long should that piece of tape be?
Most cases are cheap and will resolve this issue for you completely (and if you have enough money for an iPhone, then you have enough money for a case). I got one and the problem was solved.

UPDATE: Based on the comment, if a piece a tape really is necessary, then by the looks of this product (currently sold out) , you are looking at roughly 1 in/2.5 cm in length starting at the mic/speaker hole on the bottom-left. Good luck!
