So are you saying I was right and you were wrong ?
I see you never even started to address my point. Again for you, stay on track on this one : All units are affected. Exchanges won't help. All 100% of iPhone 4s have the issue, a 20 dbm drop when touched in the specific spot which happens to be right where you place your finger or palm in a natural way, as shown in Apple ads. Not all users are affected by a 20 dbm drop in signal because of their geographical location.
Other phones require covering multiple, larger areas in order to achieve a similar phenomenom that isn't quite as severe. The Nexus 1, the major offender drops 10 dbm, which is 8 times less severe (decibels are a logarithmic scale) than iPhone 4.
This is the issue my friend. If there really are iPhone 4s that don't exhibit this issue, what is different about them, when were they put into production and why is Apple not offering exchanges ? Answer this if you truely are arguing in good faith, otherwise, you are just denying, deflecting, spinning.
