A case for a handheld computer system is described. In an embodiment, the handheld computer system comprises a personal digital assistant. The case has multi-functional capability. The case provides a protective housing for the personal digital assistant and includes a communication module which is integrated into the case for protection against damage, whereas the communication module transmits and receives data for the personal digital assistant. In an embodiment, the communication module comprises a radio frequency (RF) wireless communication device. In an embodiment, the case includes a connector which couples to a communication port located on the back of the personal digital assistant, whereas the connector couples to the personal digital assistant inserted inside the case. In an embodiment, the connector comprises a latching connector which electrically couples to the communication port and which couples to the personal digital assistant. In an embodiment, the latching connector couples to the back cover of the case such that the latching connector can be rotated about a pivot axis to a latched position and to an unlatched position. When the latching connector is rotated to the latched position, the latching connector latches to the back cover and couples (electrically and physically) to the personal digital assistant inserted inside the case. When the latching connector is rotated to the unlatched position, the latching connector unlatches from the back cover, uncouples (electrically and physically) from the personal digital assistant, and rotates through an opening in the back cover to a position outside the case.
