Hey guys, Im going to be receiving my iphone 4 tomorrow that I ordered from AT&T premier site. Now with all these people having issues with the antenna and proximity sensors, it makes me wanna return the phone back without opening it. Im left handed so the signal drop is gonna be a big problem for me. I wasn't aware of these issues when I first ordered this phone. I really don't want to open the phone and pay the 10% restocking fee to return it.
