I have to vote Verizon too I work out on the island all the time I live in central nj I work in jersey city and I drive a tractor trail or I usually run out to syosset li (exit 40 on lie) and sometimes run all the way out to some of the winery's on the eastern most tip of the island also ocasionally run upstate to syracuse and have never lost a call with my I phone 4s I also have it jail broken and can use my Internet while on a call.... I have had many phone issues with my old android and had it replaced 5 different times no questions asked maybe its just the luck of the draw on we're you are getting your phone serviced... I did mess up my I phone when I first got it and was jail breaking it and they next day aired me a new one.... No questions asked. Of corse I didn't tell them I froze the phone while jail breaking it...
