The IPhone SDK core location services are notorious difficult to the debug. The documentation is somewhat sparse, the example code works, but what all the parameters really mean and do is not clear. The precision of localization crucially depends on reception, the more towers the better, and, if you are lucky, a clear sky for GPS.

After a first misguided attempt to improve my localization modul (I introduced a cut on the precision of 1km), I went with “take what you get”: ask for the best precision and take the first location, which does not come from the cache. It probably won’t get any better.1 Let’s see how this one works in the “wild”.

1Of course, this not for precision GPS tracking. But for your standard location aware App it should be fine.
