One nice employer tells me that it is OK to return an iPhone, after talking to the store manager. Went back to hotel to bring some phone accessories, waited for a 45 minutes line, another employer tells me now that it is not OK to return it, need to pay the termination fee, after talking to the same store manager. Wasted a lot of time and nerves. Confusion: 30 days from ordering date of a new phone or shipment date? Who knows ... Why returning? Because of many dropped calls and poor signal. AT&T fault, iPhone fault? Perhaps both of them. On top of this, I am traveling and reset the phone for return, now I need to be near my computer at home to get it working again ...
