How does the location get updated?

I have written a Java app that runs on my phone. When it's running, it updates every 60 seconds, and is very accurate. (+/- 5m). If you have a mobile phone that supports J2ME and JSR-179, you can do this. The Nokia N95 is what I use. The N80 (updated to N80 Internet Edition firmware) will also work.
Each update packet from the phone has been made to be as small as possible, and is currently 40 bytes.

Why not see the extents of my journeys with this system?

How accurate is this?

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.
