Any idea if this will work in the non-GPS model using the cell tower locator?  The site does not seem to address this.

Just downloaded this cool App from Apple's site onto my Iphone. It is currently
reporting my position being near Pittsburgh.
Wished I had this app while I was in Brazil this past january.

The iPod touch is limited to WiFi determination. That is pretty accurate (the range of a wifi signal - say 200 feet) for access points the system knows about, mostly public hotspots. Unfortunately there is no way to register the location of other access points, so it will not know where it is in your home and other private places you visit.

Glad to see this got approved, my quick and dirty app which just did position (not messaging like this one) was rejected three times, I'd given up trying. First was for limited audience, second was for a memory leak (30 bytes every time the program was run, hardly a crisis), and the third time without a specific reason. I've heard free apps are less likely to get approved than pay ones, but I wanted mine to be free. Oh well...

I used my app on a trip from the Keys to Tallahassee, see

I only ran the app intermittently, I was in a park vehicle with a single power port, and running the GPS in the iPhone really sucks power, but it worked everywhere along the route. Compare that to this

http://www.findu.com/cgi-bin/track.cgi?call=k4hg-5&geo=usa.geo&refresh=63&start=999&zoom=2

which is a VX-8R running all the time with a three minute rate. For those that travel outside of cities, even within, the internet has become a much more reliable transport medium than the APRS network. W7LUS has known this for a while ;-)

For those that use the iPhone, look at these pages, which use the iPhone CSS to produce a familiar UI.

The www1 is required for now, I have not loaded this on the backup server.

Follow the radar link, this uses zoom to produce an image optimized for the iPhone display, and can be pinch-zoomed for more detail.

Neat. It's nice to see Apple let this past their gates despite APRS's
"small" userbase.

Does anyone have a report of how it works on the iPod touch? I may
purchase this later if it works. I think the positioning in the iPod
touch is based on IP address, so I doubt it could be very accurate.
