Within hours of customers receiving their initial pre-release iPhone 4 shipments, we began to receive reports of reception problems.
The problem occurs when users squeeze at the antenna locations on the iPhone 4, on either side of the casing. Squeezing, effectively shorts out the cell phone antenna and causes the signal to drop off. The issue appears to be a hardware defect, and in our opinion is unlikely to be fixed by any software update released down the road.
This may cause huge problems for Apple in terms of product recalls. One possible solution for Apple would be to give away the iPhone 4 bumper cases. Those cases would likely decrease the pressure on the casing and provide at least a short term solution.
The video below confirms this issue.
In addition to the reception issue, we’ve heard our customers complaining about sound quality issues and screen blemishes. We’ve also had one report of the iPhone 4 getting very hot to the touch.

No pressing hard is needed. It is the capability of the human body to act like an antenna (shorting the RF) that is causing the problem. It makes the vertically-polarized GSM L antenna become low-performant as it completes the metal loop.

GPS = 800Mhz.
GSM = 900 to 1900Mhz.
Wifi/Bluetooth = 2.4 Ghz.
When both Antennas meet, the electrical circuitry on each wireless pcb module would be confused.
So it is a hardware/firmware issue.
