Sorry if the sarcasm didnt come through, I'm not really mocking lefties :P It's a nice suggestion but really it's not necessary. We have an iphone4 here and we don't have the problem with covering that part of the phone with our hand that others are facing, signal isnt dropping - however I think it's worse if you have sticky palms. We could lick our hands first to try that out but no way we'd be allowed to get spittle on the development tools :P Really, it's easy to just adjust your hand to avoid covering it anyway if it was a problem. Being right handed Im not fussed either way It's a silly design flaw but it's not much of a big deal in my view
