The new iPhone's signal reception can be weakened if you don't hold it correctly. That's what Apple told Engadget Thursday. Apple's latest device went on sale on Wednesday, with hundreds of people queuing outside stores for the launch.

Many users have complaint for the poor signal reception of the new device. Social networking site Twitter was full of chatter, with numerous tweets on the reception problems.

The issue might stem from the way the integrated antenna is constructed. One section provides mobile reception, while another is for wi-fi. Some users have speculated that touching the bottom of the phone bridges this gap, affecting signal strength. In addition, the casing of iPhone 4 is made of stainless steel, which could also serve as its antenna.

Jobs refered to the issue related to the mobile phone signal. Since it's a matter of the physical location of your hand in regards to the phone's antenna, Jobs suggested users to move their hand position, or get a case which covers that part of the phone, thus breaking contact.

Apple's official response reads:

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.
