Apple released the iPhone 4 with a potentially critical flaw. If you hold the iPhone a certain way, the device will lose it’s signal, as the antennas are placed on the left and right side of the device. The flaw is especially bothersome for left-handed users. Apple’s response will not go in the textbooks for the best ways to handle a bad PR situation:

“avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band.”
