I have an old iPhone4, that has been susperceeded by my iPhone5 for normal phone use, that I use with Harry's Lap Timer for capturing lap times at track days. I also use it with a Bluetooth GPS receiver to give higher GPS sample rates. The iPhone4 samples GPS once a second, with the GPS receiver, it samples 5 times a second and their are more expensive units that sample at higher rates.
