Is there anyway to use GPS for IPhone 3G TOTALLY free?

Is there anyway to use GPS for IPhone 3G TOTALLY free? I know GPS is free but since Google Maps is not included in the phone, it is required to be downloaded every time GPS is used. Is there anyway to store the maps in the phone to make it totally free or is there any other method?
