Does one need to be an engineer to understand that it either works or doesn't work?
If you touch the black line and the phone completely stops working, it stops working.
Unless you are grabbing the phone from th top (which I am right now), I can't imagine typing on this thing without it losing signal completely. I missed 5 phone calls in 30 minutes while checking e-mail.
What if one of those calls had been an emergency? That's why this phone is going back. I'll eat the restocking fee, and go from there.
I consider myself a fanboi, but I can't believe how many 'kool-aid' drinkers there are on this forum. Apple can do wrong. I suppose some people walk through life with blinders on for more important issues than this, so why not a phone.
