What with the iPhone 4 pretty much taking over the world this week – queues outside the flagship store in London, units flying off the shelves in the US – it’s been a pretty good news week for Steve Jobs and co. However, one minor bug has been found with the new smartphone and as many left-handed people have suspected for a long time, this bug is more evidence that the world is against them.

‘Connectivity bars start melting away one by one after the skin of the palm came in contact with the lower left-hand corner of the unit’

According to a report in Dvice, “This could be the weirdest bug to hamstring a phone in a while. Left-handed callers are finding a serious drop in signal strength when using the iPhone 4. It’s thought that when one’s palm covers the bottom left corner of the phone it hampers the iPhone’s ability to make calls.”

Engadget first found out about the bug apparently and bought two new iPhone 4s before watching the connectivity bars start melting away one by one on the UK’s O2 network after the skin of the palm came in contact with the lower left-hand corner of the unit, where the WiFi and 3G antennas meet.

“If we had to guess, we’d say that our conductive skin was acting to detune the antenna,” Engadget’s Richard Lai writes. “In fact, we’ve already managed to slowly kill two calls that way so it’s not just an issue with the software erroneously reporting an incorrect signal strength.”

A rubber sleeve designed to fit the iPhone 4 can fix the issue as it puts a layer of rubber between your flesh and the phone, and helps calls go through. It’ll set Irish lefties back around €30 when it’s released though.

As Dvice puts it, “Seriously, did Apple not have any left-handed engineers?”
