Did you look at the article that Joe posted about the iPhones/iPads Russ, and their abilities? Didn't mean to hijack, but Joe started it..LOL
"read with concern a recent report by security researchers that Apple's iOS 4 operating system is secretly compiling its customers' location data in a file stored on iPhones, 3G iPads and every computer that users use to "sync" their devices. According to the researchers, this file contains consumers' latitude and longitude for every day they used an iPhone or 3G iPad running the iOS 4 operating system — sometimes logging their precise geo-location up to 100 times a day. The researchers who discovered this file found that it contained up to a year's worth of data, starting from the day they installed the iOS4 operating system. What is even more worrisome is that this file is stored in an unencrypted format on customers' iPads, iPhones and every computer a customer has used to back up his or her information."
