IPHONE 4: APPLE SELLS 1.7 MILLION HANDSETS IN JUST THREE DAYS

Apple has sold more than 1.7 million of its new iPhone 4 handsets in just three days.

The upgraded model, which features Apple's high resolution Retina display and a new video calling system called FaceTime, has been a hit for the tech giant.

But for left-handers, the placement of the handset's antenna - which is located on the lower left corner of the phone - has proved problematic.

An Apple spokesperson said: "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.”

CEO Steve Jobs added: “Just avoid holding it in that way.”
