So what would one do with a cell phone with an embedded gps assisted inertial guidance system? Tape a rocket motor to the back for a new way to destroy the iPhone?

ST makes a 3 axis mems accelerometers that speak SPI [and I2C]. VTI has I2C only and SPI ones. I have the SPI/I2C one [LIS3LV02DL] made by ST but I don't have it working yet. I'm still in awe of how small it is -- much smaller than a tic-tac candy. http://www.digikey.com/scripts/DkSearch/dksus.dll?Criteria?Ref=197587&Si te=US&Cat=35783228 http://www.st.com/stonline/products/literature/ds/12094/lis3lv02dl.pdf It was ~$14. Dirt cheap for what it does. If what people say about "wasted space" inside the neo is true then I'm hoping to cram one in there when I get my phone. Maybe some mems rate sensors too.
