Fasterfix app from market

read all of this post so you don't screw yourself.

Instructions:

To speed up google maps nav: Install "Fasterfix" app from market, open app, accept super user permissions, pick region, reboot, then test via google maps navigation. Should speed it up $hit load, just as fast as my incredible when it was new. Hope this helps

Honestly until android comes up with a fix for the maps app I'm going to use WASE GPS found in market you MIGHT get a search for SIGNAL, BUT MUCH FASTER GPS.

FYI!!!!!!!! DONT REPICK REGION IN FASTERFIX APPLICATION!!!!! or you will have to do this:

It appears I was having some issues cingularly in the davlik cache because I changed my region in fasterfix because I figured what the fnck, and that screwed up my speed so when you pick your region stick with it or you will slow the crap out of navigation plus to fix it you will have unistall fasterfix, delete" data@app-private@com.Double.FasterFix-1.apk@classes.dex[/email]" under davik-cache, reinstall pick region, test via navigation.

Info:

Sorry about last post: you will only need to open Fasterfix app once.

Misc:

It appears that fastfix is server based location finder, what ever that means
