GPS Question

[GreenScrew]

I flashed my xv6900 with scrosler's hacked/leaked official Verizon ROM. Everything is working fine. I then went to follow the Verizon aGPS fix from xda and made the QPST changes but couldn't find a good link to the "GC Verizon aGPS.cab" in order to install per the write-up. It sounds like this is registry settings changes? In any event, I went ahead and loaded Google Maps and the GPS shows to be working just fine inside my house. Leaves me wondering if I need to make further registry settings changes or find the cab to make these changes in order to optimize the GPS functionality? What are these registry settings for? Anywhere I can find the GC cab file if I should still run it?
