I've come to the conclusion that every iPhone 4 probably has the same antenna problems (dropping signal when bottom left corner is covered) but some aren't seeing it due to the strong signal in their area. I love in Boston and when I'm outside, my signal does not drop 1 bar when I try to bridge the antennas. However, when I'm inside my office (and still have 5 bars), my signal drops down to 0-1 bars. My friend who lives in Rhode Island claims that he has the exact same situation. When outside in Providence, he sees nothing, but when inside his office, it drops from 5 to 0-1 bars. He also lives out in a suburb and it drops every time. I bet those NOT seeing the signal drop are just in higher signal areas, and would have to move out of those areas until they see the signal loss. It has to be a hardware issue. Data speed tests completely tank when the antenna is covered versus not covered. My prediction is a recall. Thoughts?
