Abstract: Improvements in a cell phone or PDA case are disclosed. The improvement includes the retention of a cell phone to allow for complete functionality of the phone while it is within the case. The phone is cushioned and protected within the case where it is semi-rigidly held. The case further includes an operable back cover where interchangeable trays can be installed where the trays provide a variety of function such as holding makeup, pills, money, credit cards, key(s) or other items a user might normally carry. A dust flap protects migration of makeup into the phone area. The door(s) can open from a variety of methods including hinged, sliding or rotating and be retained closed with magnets or snaps. The opening of the door may also activate an integrated light or alarm.
