Location permission alert on iPhone with PhoneGap

You need to do the geolocation after the device is ready. The following Jquery code, for example, will geolocate without that nasty alert:

$(function(){
  document.addEventListener("deviceready", onDeviceReady, false);
})

function onDeviceReady() {
  navigator.geolocation.getCurrentPosition(onSuccess, onError);     
}

function onSuccess(position) {
  // your callback here 
}

function onError(error) { 
  // your callback here
}
