I am a big fan of iphone and I am going out to buy a new smart phone. I really want an iphone4, so I pulled up some issues about it such as when you hold the phone on the left bottom of the phone it apparently drops calls and gives very low signal. I’m a left hand user so this will most likely be affecting me a lot if I buy this phone. Is this because of the iphone antenna, I really want to take your views about it. Please help.
