mobiles that have a touchscreen + call/discard or menu-home-return keys are referred to as full touch mobiles. all the androids & most of nokia's touchscreen phones are full touch.
difference between resistive & capacitive in short is capacitive screen respond better to touch. sensitivity can even be programmed (heard somewhere). so its likely to register a touch better & also the sensitivity will last for many years whereas resistive screen become unresponsive (sensitivity lowers noticeably) in 2yrs or so.
