In your letter, "Regarding iPhone 4," you conveniently overlook the firmware update to the iPhone 3G that implemented Apple's own proprietary formula for calculating bars of reception. Instead, you "...were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength."
I vividly remember the nightmare with the first three firmware releases of 2.0. One aforementioned release magically increased service in my home from 2-3 bars to five bars on AT&T's very same network. I say magically because it occurred in the time it took to upgrade my 3G to 2.1. I can tell you that my home was actually seeing between a -93 and -85 dB.
Unfortunately, the ability to input *3001#12345* has been removed in iOS 4. A solution exists courtesy of the AppStore, Speedtest.net allows the iPhone 4 owner to quantify the cellular attenuation they experience. I've attached three results (each performed three times and the high and low results were dismissed). In "Antenna Results.pdf" the first was recorded laying iPhone 4 on the desk. The second, touching a single finger to the left gap on iPhone 4. The third, gripping iPhone 4 naturally with my left hand.
I apologize for the verbose response; the results speak for themselves. Having waited faithfully in line for every iteration of iPhone since 2007 (nine hours this launch) it's not without anxiety and regret that I return iPhone 4. The iOS experience is unparalleled in the industry, but I require a phone that excels at making calls (any way it's held) and a company that will offer more than a band-aid as assurance.
Sincerely,
