yes, quite possible that i was unknowingly depending on 3G connectivity for the map apps.
can anyone verify that your average smartphone can get a GPS lock while 3G is unavailable?
i guess another way to ask that is does your average smartphone _always_ depend on 3G (for whatever reason) when it comes to GPS? it seems to me that they could well be separate and independent functions, or they could just as easily be interdependent (again, for whatever reason).
i'll be testing this myself next time i'm out now that i have GPSTest to check, but it would be good to hear what other folks have experienced.
on another note, anyone tried the GBOpen offering(s) from the-thorns.org.uk? site says "Garmin-compatible GMAP format". sounds like these are inexpensive, hand-tweaked vector maps largely based on OS's OpenData and the OSM product. could be a good thing.
