How to access GPS data from command line on jailbroken iPhone
I've come along something very similar a while ago but there was no package needed. I'll try my best to explain how it worked. Firstly, an iTunes backup is required. Next, you will need to access that backup on your computer. There was a program for OS X (and probably for Windows too) that could read these backups. In the backup, there is GPS data that can be accessed but is useless without the other program. It is called iPhone Tracker. Also, another option that I have not tried is this. Other than these two methods, I am not sure of any other methods. Hope this helps!
