First off, make sure you are using a file explorer that can navigate up to root (if your highest directory is /sdcard/ you need to check the program's settings; root is just a slash with nothing following) and mount /system/ as writable. A lot of people recommend root explorer, personally I use ES file explorer, which has these options disabled by default but they're there.This sounds like something I need badly. Unfortunately I'm still uncomfortable playing with the scripting or finding the proper place. Could someone please post directions of where to paste (GPS.config?)? Sorry for the noobness but am still learning and willing.
Navigate to /system/etc. The gps.conf file is here. You can copy it to your computer and modify it according to the OP. Then just replace the one that's there with your modified version. Easy-peasy!
