A circuit for use in a wireless communication device includes a on-chip
gyrating circuit that generates a motion parameter based on motion of the
circuit. A GPS receiver receives a GPS signal and that generates GPS
position data based on the GPS signal. A processing module processes the
motion parameter to produce motion data and generates position
information based on the GPS position data. A wireless telephone
transceiver generates an outbound RF signal that includes outbound voice
data and that generates voice inbound data from an inbound RF signal.
