I have tried this for the first time, and it worked. I installed GPSJinni and Mapper. My first trial is GPSJinni (Satellites), then after a few minutes, I started Mapper (GPS tab). It suddenly gets a GPS fix when I noticed GPSJinni's satellite bars turned GREEN which took 5-7mins. I opened Ovi Maps, cancelled network connection prompts, then voila! I can see my location on the map with a RED dot. *I just worry about Mapper as it sometimes crashes at random startup. *I haven't tested yet if it was GPSJinni which really caused the GPS fix, or if it's Mapper.
