In essence, Apple cops to the fact there are reception issues with the new iPhone -- namely, that if you cover the bottom-left corner of the phone and bridge the gap between the notch there with your naked flesh, you could see some signal degradation. Yes, you read that right: it's not a software or production issue, simply a matter of the physical location of your hand in regards to the phone's antenna. The company's suggested fix? Move your hand position, or get a case which covers that part of the phone, thus breaking contact. As you can see in the email above which just arrived in our tip box, this is a sentiment which runs pretty high at the company. Here's the official statement:
Gripping any mobile 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.
