Using the GPS Features on Cell Phones?

Rylor asks: "A couple of years ago I bought the Samsung 300NP cell phone, which has a GPS feature that I can turn on or off. The primary purpose is to meet the Emergency 911 calling requirements laid out by the FCC. I've checked the manual several times and it only says that I can use the GPS feature for anything service I want, but that's it. Sprint doesn't offer anything else about it. So my question to Slashdot: if you have a cellphone with this feature, what cool ways are you using it?"

Killer app for cell phones

Use the GPS to create a map of all the areas where the phone works reliably, and where it doesn't work... aren't digital phones constantly touching base with the cell towers anyway? Then they could get rid of that obnoxious guy constantly walking around saying "Can you hear me now? Good!"

Yeah, just to amplify on the parent post, it's really useful when driving. Yesterday, for instance, I got turned around as I was driving, and the GPS on my cell phone really came in handy for figuring out which direction I was going, without even pulling over. See, with my left hand I used the cell phone to get a GPS fix, while with the right hand I sketched a latitude-longitude grid on the inside of the windshield using a red grease pencil. I marked my location on the grid, and then after traveling another couple of blocks, I repeated the process and marked my new location on the grid. Voila, that told me I was driving west! The only real problem was that the grease-pencil diagram was a little hard to read, because the setting sun was in my eyes.
