Hi,
I decided to try "Network based" location for an approximate location method, and this is what I've got:
I get located near the same longitude (-70) but in the wrong hemisphere (+33 instead of -33)
btw I'm located in Santiago, Chile, so the found location around -70,+33 is just the other way from the equatorial line (it's close to -70,-33 here)
device is n95-3, software 20.2.011, location sever: supl.nokia.com and the APN is he same that works flawlessly w/ assisted-gps
