Apple obviously cannot state the true reason for the much-hyped signal-strength reduction “flaw”.

The truth is, it’s not a flaw at all, but a life-saving feature. The media seems to have forgotten the research stating that cell phone radiation causes cancer. The iPhone 4 features a new sensor that detects how tightly you’re gripping the phone/antenna. If your hand is covering a sufficient enough portion of the phone/antenna, or most noticeably bridging the break between the two antennas, the phone automatically decreases the signal strength to protect you. If you release your gorilla-grip on the phone and hold it with safe, minimal contact, or add a buffer between you and the antennas, the phone can continue at standard strength.

Obviously Apple cannot advertise this feature to the public, as tag lines such as “kills you slower than the Droid” and “Now with less cancer!” perform poorly in focus groups. As a result, Apple must deal with unfair bad publicity. But, in the end, it’s a strategic business move, because the iPhone 4 customers will live longer than Apple’s competitors’ customers, allowing them to buy more phones in the future.
