There is no truth to the following iPhone 4 rumour. In fact, I created it.
Despite Apple's insistence that they're at fault for a defect with the internal software displaying the wrong number of bars for the apparent signal strength, too many reports are adamant that the issue is real - that it is easy to short out the two antennae (WiFi and 3G) by touching the case in the wrong place.
Today we have much stronger proof.
Consumer Reports, America's equivalent of Australia's Choice Magazine conducted detailed measurements on the performance of the iPhone 4.
Using a Faraday Cage (which blocks all radio waves from the outside coming in and from the inside getting out) the organisation controlled the iPhone 4 with a mini base station inside the cage.
They definitively found that touching the phone in the lower left corner to short the two antennae together gave a significant reduction in signal - enough in many situations to cause a call drop-out.
On this basis, they refused to recommend the phone.
