Ideally, neither. If all goes well, on Friday I'll be releasing a
LocationPoller service that will handle this scenario, though I don't
recommend trying to get locations already at boot time (wait a couple
of minutes via AlarmManager).

This will leak the listener, until such time as Android gets rid of or
recycles your process. This is not a good strategy.

Yes, though Android Market users tend to greatly dislike this.
