you got it messep up.
using PAPAGO, will require GPS to be turn on. but without packet data enable (standard GPS, not AGPS), this will greatly depend on your location and will take more than 2mins to connect.
but enabling packet data (AGPS), this will help you connect in less than 30seconds, provided it can get connected to Internet to download AGPS data.
using network location (wifi / mobile network), this can be use for latitude, twitter geolocation and sort of.
I think you maybe messed up on the last part. Android have two features to pinpoint your location. One using the hardware GPS which you elaborated clearly, the other one is using wi-fi / mobile network.
For a simple test. Try run Maps and see that it start with a large radius (accuracy) then it reduced to smaller and the accuracy range decreases. The first time you fire up the Maps, it will use the readily available data which is wi-fi (based on IP) or mobile network (based on telco tower triangulation), then when the GPS lock up, it will use the latter as it is more accurate.
That is why sometime we can have GPS location while inside the building although most of the GPS hardware are struggling to get signal even PND unit.
Wifi/mobile network is not A-GPS.
