i think the jailnreakers might want to know about this. i know yall have heard over the web and news how your ipad and iphone secretly stores location info on you into a non encrypted file on your device. like where you have been, giving time stamps, longitude, and latitude info. this can be accessed by anyone if they connect wirelessly or whatever to your device.
i read on redmondpie.com that there is a new jailbreak tweak to stop that. its a free tweak and is in the Big Boss repository. its called "Untrackered". once installed, theres no icon or settings to mess with. ot runs in the backgroumd as a daemon. it continuously cleans up that location info file where the info is secretly stored at.
