I am not dissing you or this patch but honestly trying to understand how Jelly Bean gps works and how this patch works. Can you help shed some light on this?
Your discussion goes back to the "gps.conf is no longer used" comments made from ICS onward. Before even trying to claim I'm right, let's look at what another manufacturer did with my patch.
The ASUS Transformer Prime had no gps.conf. It had horrible performance and is running ICS. After many ignorant "attempts" to resolve the problem, half of my conf configuration appeared in the gps.conf in a firmware update in February or March, after I released a customized patch for that device to get its GPS brought to life. I have an ongoing disput with ASUS for not even saying thank you. But, ASIA doesn't see the need for that as it was freely put out in the community. I guess thank's aren't nice.
Now, it is true that the gps.conf is not the only GPS controlling file now. But, that doesn't discount its current importance. There is an XML file many times found in /etc/gps/ which have device specific driver and /dev/ information. However, the XML file DOES NOT take important parts of the aGPS solution into the equation...yet.
So, the "new way" only covers about 2/5 of the ground to get to away from the gps.conf. What's more, the system still looks for and reads the gps.conf as insinuated by the ASUS statement above.
I bought two GNexus Maguro's and received them this week. GPS was running pretty good. But, the patch did help a bit. I may consider building a custom patch for the device but I'm not so sure it's necessary based upon my own observations.
EDIT: Also, there is a gps.conf in /etc/ of the stock JB ROM released by El Goog for the Maguro...
