i have no specific idea what they're trying to say @.@
you can' hold your iPhone 4 however way you please.
u can hold anything however way you want to
and..... don't we all hold it anyway we want it? (assuming we all have it) it's not like anyone's going to hold it in an uncomforable way?
if you hold the iPhone 4 with your left hand its likely you'll kill your phone signal
mhmm.. good for him! i'm a left hander!! Yayy!! LoL
