Apple has posted a new webpage to demonstrate how different grips cause attenuation on many popular smartphones.
The opposite of amplification, attenuation happens whenever a signal is obstructed. All antennas — including television, radio, GPS, and cellular antennas — can experience attenuation. And with most antennas, the density and composition of the human hand can cause attenuation to a greater degree than some other materials. On a mobile phone, signal loss typically occurs when your hand attenuates the most sensitive part of the antenna. In the photos and videos below, we demonstrate how different grips cause attenuation on many popular smartphones — including iPhone 4 and iPhone 3GS
BlackBerry Bold 9700 In our tests, the BlackBerry Bold 9700 dropped from 5 bars to 1 bar when held in a way that attenuated the signal.
HTC Droid Eris In our tests, the HTC Droid Eris dropped from 4 bars to 0 bars when held in a way that attenuated the signal.
Samsung Omnia II In our tests, the Samsung Omnia II dropped from 4 bars to 1 bar when held in a way that attenuated the signal.

Apple Spin Doctors: Do not rationalize it. We (owners) could care less about other smartphone manufacturers. You are held to higher standards. It is pathetic, almost to the point of obsurdity, when an attempt is made to excuse a design flaw and/or defect. Today, the issue was addressed and a resolution plan was implemented.

Of course it's on AT&T! Poor service, drop calls, and many other issues! What more can you expect?

wow, i just tried my sisters blackberry 8900 on tmobile, and it dropped bars! not drastically, but it did, it was at 4 bars, and when held in a certain way it dropped to 3 instantly, and sometimes 2 after 5 seconds, and when let go goes back up to 4 in about 5 seconds, tried it 5 times worked every time, still not as bad as 1 bar or no service tho
