You guys must have incredibly dry hands or just live in an incredible service area...
Nope sorry mate.
Even when Ive got two bars due to poor coverage it still wont drop.
Place the phones left corner into your palm, wrap your palm around the phone. Make sure your SKIN is touching the black break in the antenna on that left side. Count to 20, slowly.
That seems to replicate the issue for more. I myself have no signal issues either. Just saying.
I have the 16GB iP4 and holding it normally, in my left hand with the base of my thumb bridging the gap on the lower left side of the phone, I go from 5 bars to 1 and occasionally then lose all service. I've also had issues with bluetooth reception - with people telling me I'm either very hard to hear or that there is a lot of static (using the same jawbone I used successfully with my 3G).
Tried the wide rubber band trick and sure enough, it fixes most of the problems. I'll go pick up a bumper today and see if I can get it free - I already have a complaint in with Apple and free bumpers was suggested to me as a possible fix by a senior iphone advisor.
+1I can wrap my whole hand around the phone and it wont drop.
All iPhone 4s have the "problem"... It's just a matter of whether or not you live in an area where the signal is susceptible to attenuation.
Uh... no? I've tried in different environments including the subway and in the middle of a concrete building.
