The problem seems to be founded in bridging the 2 antenna's (wifi to 3g) as this youtube video shows: http://www.youtube.com/watch?v=zvH-i7rKPJc&feature=player_embedded
Simply placing a key between the 2 causes the signal strength to exhibit the same issues as holding the bottom left corner with your hand.
Various people must be more or less conductive resulting in you having issues or not...
The phone having issues with a hand covering the antenna & smothering the signal is one thing (& common with other phones 2) but this seems to indicate that it's a design flaw as bridging the 2 antenna's with any conductive material (be it a key or a hand) appears to be what's causing the signal degradation.
Can anyone else with an iPhone 4 try this & see if it's repeatable?
