What"s the easiest way to get the current location of an iPhone?

I already know how to use the CLLocationManager, so I could do it the hard way, with delegates and all that.

Optimizing CLLocationManager/CoreLocation to retrieve data points faster on the iPhone

I'm currently using CoreLocation + CLLocationManager in order to compare a users current location to N amount of other locations. The problem I'm facing is I'm dealing with urban areas where locations are close to each other, so I need to pin point the location of the user as accurately as the device allows without sacrificing too much time. My calculations are darn accurate, the problem is, it takes far too long to collect 10 samples. I'll paste my filters/accuracy respective code below. If anyone can comment on how I can speed this up, that would be great. Until I speed it up, it's rather useless in my app as it currently takes around 3-4 minutes to gather info, a duration that's not accept by my target demographic.

What causes (and how can I fix) this odd Core Location error?

GPS and draw MapRout in iphone

I have a latitude and longitude that is fixed, so I used that and got the point in mapview with pin. Now I want the current location and draw route, so I think using gps I get the latitude and longitude. Using this location(latitude & longitude) I have to draw a route with my fixed value (latitude & longitude). How is it possible..? Is this is the right way to do it? ?How to draw the route with two point..?
