So, the reader who has initiated the iPhone 4 reception discussion sent an email to Apple’s CEO Steve Jobs and asked the following question:

“Non issue. Just avoid holding it in that way.”
Apple’s official statement on iPhone 4 Reception
“Gripping any phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone. If you ever experience this on your iPhone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band, or simply use one of many available cases.”
