Am been using Nokia E71 symbian smartphone since some time. Only flaw is broken chip of lower right corner of the phone. which doesn't affect working of phone in any way. The flaw can be seen in photo. it has memory card slot and USB type B input. charging is by small pin of original Nokia phone. It has a 2.5 mm jack (not 3.5 mm). Charger is not included. video shows functioning of phone and also the chipped corner of phone
