I've just come from an iPhone 3GS on O2 in the UK, to a 4S on Vodafone. I live in a fairly rural location so reception has always been spotty for me, but Vodafone at least offers 3G in the nearest town where I work, unlike O2, and their 2G at home is a little better too. Combined with the antenna improvements in the 4S I was expecting things to be much better and on the whole they are. One thing bothers me though. At home where I generally have 2-3 bars, I can make them disappear almost immediately just by covering the antenna join on the lower left - from up to 4 bars to "No Service" in a matter of seconds.. A fingertip will do it, a palm works even quicker. I never owned an iPhone 4, but surely this is the famous "death grip" I heard so much about? It works regardless of whether I'm touching the side of the phone anywhere else. What happened to this dual antenna and automatic switching? In fairness, the old 3GS (which now has my wife's Vodafone sim in it) will drop bars just as quick if gripped by that corner, but that never made the same signal claims and doesn't have a single line on the bottom left which can compromise the antenna with a single misplaced digit. Am I expecting too much here or is there something wrong with my 4S? I'm looking forward to testing it tomorrow at work where there's strong 3G signal - if I lose bars in those conditions something must be wrong, right?
