So the other day I got bored and decided "I'm going to learn a new technology". Then I got unbored. A few days later, I decided on Core Location, the iPhone GPS framework.
I don't actually have an iPhone, only an iPod touch, which doesn't have a true GPS but relies on nearby routers to get coordinates. Apparently it downloads all nearby MAC addresses because I was able to keep a fix for a few minutes after leaving school with no internet connection.
Anyhow, using Core Location and Map Kit, I tossed together a cool little app that drops a pin wherever you are, whenever you get a GPS fix (technically, every time Core Location updates your coordinates). A few tidbits of code are here (http://wjlafrance.wordpress.com/), but the coolness is the end product. See attachment. :)
This is probably going to be my "I did something new that doesn't deserve it's own thread" thread.
