You are misinformed. Assisted GPS is simply a feature that reduces the time-to-first-fix of GPS. Triangulation from cell towers exists, but nobody calls it A-GP

I've used the iPhone 3G, 3GS, 4, and 4S extensively in the wilderness. Every version since GPS was introduced has been "real" GPS.
- mikeash 14y agoI'm not talking about cell tower triangulation, I'm talking about offloading computation to more capable hardware located remotely. It exists: http://en.wikipedia.org/wiki/Assisted_GPS#Modes_of_operation http://en.wikipedia.org/wiki/Assisted_GPS#Modes_of_operation I can't find anything about chipsets that only do that, but I'd be surprised if nobody had ever done it.
