There are a lot of affiliated cell phone shops in Sunset Park. And some of them are quite good and after a while pick up a reputation. The guy who runs it is a young entrepreneur who gives his customers a fair price, puts in long hours and provides personal customer support on the products he sells. Try him out, drop in and visit and say hello. Tell him you saw his store on this blog. He's on the corner of 58th and 5th Avenue.
