iPhone 4 Antenna issues: Software or hardware.
Category Video | Saturday, June 26th, 2010
n looking at what is happening, the root of this problem is in the hardware. When you physically bridge two parts of the phone with your hand the signal drops, and then reappears when you change your grip. This happens because of interference in the RF signal, where the user’s hand will either shield, ground, or introduce noise in the signal.
