This looks like requesting an approximate position assisting the gps to to get the precise position. I'd bet all agps devices do it in this way; before the confirmation dialog, because it gives the optimal user experience. If they waited for confirmation to download the agps data, you'd haveto wait more to grt your location. Even if you don't want to get your location now, it makes sense to cache them because you are likely to want it in the near future. These are the same data iPhone was found to cache and back up.
