The launch of Apple's iPhone 4 in the UK, US and some European countries on Thursday, has been overshadowed with issues surrounding signal loss when the device is held in the user's left hand.
"The videos embedded below shedding light on the cause of the problem. It seems that Apple's new antenna technology is failing when the bottom left corner of the iPhone 4 is touched. In that corner, the two available antennas come close to meeting. When connected to each other by a person's hand (like when held in the left hand), some sort of interference occurs, causing the signal to degrade and eventually drop the call."
Apple is reportedly handing out free iPhone 4 bumpers to customers in the UK who return to Apple stores and complain about the issue.
A user even pinged Steve Jobs' email address and got an odd reply:
"Just avoid holding it that way"
