ConclusionsConclusions

Exact GPS locations isn’t guaranteed using Exact GPS locations isn’t guaranteed using cell phonescell phones

Cell phone service GPS is easier obtainable Cell phone service GPS is easier obtainable

Emulators were complicatedEmulators were complicated– i730 bad with web servicei730 bad with web service– Wireless toolkit bad with GPS coordinatesWireless toolkit bad with GPS coordinates
