There’s comes a point in the development of every device that users and devs alike will start rooting through their device—pun intended—and find and modify previously unknown files. Often times, these uncovered files don’t do much at all, but occasionally a diamond in the rough is found and brings some real benefits.
This is the case for the Samsung Galaxy S II I9100. XDA Senior Member Crescendo Xenomorph has stumbled across sirfgps.config within the system files that seems to have some bearing on GPS. The interesting part is, none of the current GPS enhancement mods even touch this file. Testing is still being conducted, but preliminary results show that modifying the SiRF file may yield faster and more accurate GPS locks.
Results are still mixed, and users are still trying out the various variables and seeing what each one does, but the progress and testing support from the Galaxy S II community has been nothing short of impressive. While no users have reported that their houses burned down or phones exploded, there are a few who aren’t getting the results they wish out of their modding and testing.

You’ll need to read through the whole thread, as the download links, what others have modified, and most of the information is spread out over the course of many pages. As usual, be sure to make a backup before attempting to modify this, just in case you need to restore it to stock values.
