I used the redimote 4GB .its really excellent mobile I have to say beacause it have great outside designs .and the phone have a good quality , if it fall from the great height it couldnt broke .In todays date we need that kind of instrument . Its really strong gadget I have to say beacause this is my personal experience .It have 4 fb memory we can store lot of movie , pictures or files in it.but the camera is not so nice as another mobiles . These gadget are really nice the price are also suitable and the features are also good .
