Just wondering if anyone knew anything about this...I know that A-GPS grabs info from the cell-network to find the closest satellite so you don't have the "warm up time" of regular GPS, but in the iPhone blurb Apple seems to say that A-GPS won't just use the mobile net to get this, they will be able to use a wi-fi network too?
Does that mean if someone was clever enough my wi-fi base station (with dd-wrt loaded) would be able to grab that data from the net and pump it to my iPhone? Or would we only be talking about hotspots that have a bit more complex back-end than that?
No they're referring to WiFi positioning it's not really AGPS in the sense that it will help get an actual GPS fix faster. There's a small app called GPS Info that will show what kind of fix you're getting on the iPhone, GSM, WiFi or GPS.
