How does the location get updated?

There are 2 different methods that I use.

• My work phone updates its location using cell tower triangulation between 15 and 90 minutes, and isn't very accurate. (+/-800 metres). No, you most likely can't do this.
• I have written a Java app that runs on my phone, and when I run it, it updates every 7 seconds, and is very accurate. (+/- 5m). If you have a mobile phone that supports J2ME and JSR-179, and a Bluetooth GPS device that speaks NMEA, you can do this. The Nokia N80 (updated to N80 Internet Edition firmware) is what I use.
  However, until I get a dataplan that doesn't cost me anything, I have to pay for this.

The "source" value below will tell you which was the last to do an update.

Notification

If I'm currently being boring, and haven't moved for a while, and you fancy spying on me, you can get an email when I start the GPS. When my location method is GPS, you'll get a once off email reminding you to come back here. Your email address will be deleted after it is sent.

I do leave my phones at home sometime, sleep, and go to work. So don't expect me to be constantly moving. 9am, and 5.30pm on weekdays are likely times.

Yes, I do get them. No, you don't get any notification when you send them. Yes, you need to include some contact details if you want a reply.
And just for the record, I'm not going to "run around the block" just to give you some amusement. You can put your email address in, and get an alert if I'm not moving.
