For the sake of the debate, let's say that happens. All of it, plus 2 more you didn't think of. These 6 people get together with your iPhone (which you also forgot to send the delete command to after finding it missing), root it, pull the file off (ignoring your actual data, Safari cache, and other incriminating prefs for various apps, which already has more info about you in it than this file), decode the file into actual coordinates and times using software that no doubt these geniuses wrote themselves, and semi-track your location over the last month using the sporadic cell tower and wifi references contained in this file. (remember, 2 of them already know where you work)
Then what do they do? Choose a different coffee shop for tomorrow based on the ones you've been to? Find a better/worse clothing store to shop at? Slowly learn traffic patterns from your habits to speed up their commute? Stand on a street corner that you might frequent to...idk, give the phone back?
I mean, I guess if you are a hitman for the local chapter of [insert least favorite ethnic group here] bangers, then maybe you don't want anybody to know where you've been...but I don't care if you get caught, then. And besides, you'll probably have found them first and taken all 6 out before they figure out what to do with the data.
