Hi folks.
I don't own a Saga, but I like helping out. I recently picked up a copy of HTC Quick GPS, patched it, and ported it to WQVGA for the Omnia.
Well, I attempted to do the same for the Saga. I am not sure if it will help at all, and if it does, you still need clear sky, and good LOS (line of sight) to get a GPS lock. This just attempts to make it faster.
It
Downloads a file called xtra.bin, which is used to estimate satellite position for the next 7 days. The file is specifically meant to be used with Qualcomm GPS chips, which the Omnia has, and judging from what I extracted in the Saga rom, the Saga does too.
Anyway, it may work great, it may be a dud. This app cannot make its own net connection, I dont think, so keep ion mind to establish one first. It is NOT required to keep running while using the gps.
