If your phone has built-in GPS (most do), has an unlimited data plan (internet needed), and runs Java MIDP-2.0 applications, check this out.
InstaMapper is a free service for tracking cell phones GPS locations and then displaying them in REAL-TIME on Google Maps for you to view. It’s the equivalent of sticking a GPS tracker on yourself (or someone else and then viewing where they go as it happens. InstaMapper also logs data locations, so you can see a picture of exactly where the phone has traveled in a time period. It’s entirely free and they store up to 100,000 locations per device.
Incredibly useful service, but the problem is most of us (or more specifically, our partners) don’t have cell phones that are capable of running the app, which is usually smartphones like the iPhone. It’s also sometimes impossible for a person to part with their personal self phone for any amount of time, so I have come up with an alternative.
Go to Best Buy or Target and they carry a Boost Mobile i425 prepaid phone for under $40. InstaMapper works with this phone and the unlimited data plan for this phone costs only 35 cents a day, so you should have yourself a fully working GPS tracking device all for only $40 bucks and a couple cents a day. The dimensions are like a thick candy bar, 5 in. x 2 in. x .5 in, so you can easily hide in a car… (oops, I didn’t say that).
