I live in an area where I would get around 4 bars or so BEFORE the update. After the update its more like 2-3 bars. Before and After the update I tried the death grip with and without the bumper and it still drops the signal off. Im OK with it though as I don't hold the phone that way but the bumper is NOT a fix for the issue at all. If I am in a good reception area it doesnt seem to drop at all. I like my iPhone so no plans to mess with it but I think in the future I will not be standing in line for the first run of a new one. Ill just keep mine about 3-4 months longer and get it when more of the bugs are worked out.
