“with the faster_gps_fix you may not see a faster result at first try. thats because your device have to redownload the a-gps data. so make sure you have a data connection.
you also can redownload the a-gps data manuall with a market app called GPS-Status for example.”
If this sounds like a tweak you wouldn’t mind having, the download of the file along with the instructions can be found on the XDA forums, but since this is more than just downloading an app, it is suggested that you have some knowledge of rooting to begin with. While the folks at XDA have stated that this is a pretty “nice, safe, and simple” tweak, we suggest that backing up your device and doing a bit of homework before proceeding sounds like a great idea.
