One of my favorite things on the iPhone 4 was the large "exterior" antennae that was also part of the strength of the iPhone. Apparently, Apple didn't do much testing. HTC had grounding issues, and now the iPhone 4 appears to have major grounding issues with the antennae as well. If you touch the metal band (which is the Antennae) you will lose signal completely or suffer majorly degraded signal. How this passed Apple quality control is beyond me. There are many dozens of videos showing off this and Gizmodo has bundled them all up, first one here the rest follow our link: iPhone 4 Loses Reception When You Hold It By The Antenna Band?
