Getting the aGPS to work on the XV6800 MR2

The release of MR1 and MR2 for the Verizon XV6800 has complicated things quite significantly. I had to install an older Verizon ROM, then update the bootloader, then install the new radio ROM, then install the new device ROM. Once you do that, then you need to run QPST and change a few settings to enable the aGPS.
