iPhone GPS Development - Tips + Tricks
I'm looking for some feedback, blog links, etc that offer some tips and tricks for iPhone GPS development. I've read and understand the API, I have my demo app up and running, etc but I have run into some "quirks" with gps on iphone. For example, it seems that you you will receive a lot less location updates when your iphone enters "power save" mode. I've read that you can combat this by playing music in your application [not sure if this is true]. 

It also seems that, terms of making a reasonable pedometer, you should filter out any reading with horizontal accuracies less than 20 meters. Does this sound right?

Is there any kind of checklist out on the web for iphone gps gotchas?

Thanks in advance.
