This isn't true on most phones. aGPS assists GPS to find a satelite to lock onto. it doesn't just magically replace it if it can't connect with a "rough" location.
Look it up in Wikipedia

Again, I'm going to have to disagree. All because something is on Wikipedia doesn't mean it's accurate. I'm a BSEE with over 25 years of digital chip, computer, software, and network design. I've talked to developers trying to crack the Sprint GPS issues.
You might get a better understanding of how aGPS works if you look at the mGMAPS web site. Look how the author there wrote the app, and for Sprint phones he specifically says "The QJAE GPS API (Sprint) was updated to prefer assisted-GPS over standalone GPS. This sacrifices accuracy for quicker fixes and more stable GPS positioning." Meaning that, yea, the application magically (as you put it) switches over to the aGPS system to get the lat and long coordinates if the stand-alone GPS receiver can't supply them.
Let's just leave it at we agree to disagree.
