I think I may have discovered something. When I old my iPhone in the way that is supposed to cause signal discrepancies, nothing happens. However, when my father hold the phone the bars drop. So if you have an iPhone 4 can you please answer these questions: Skin color: (not just "white" but I mean the tone) Sweatiness of palms: Rate 1 to 10 Height: Roughness of skin: Rate 1 to 10 If you have someone else hold it does the issue still occur? Thanks for the help, and with any luck we will come to find the common denominator of all the people who have this problem(if it is not the phone itself).
