I'm merely stating this:
1. E911 Location Service can take place with no service contract (phone or data) regardless of the type of A-GPS. This is government mandated.
2. Nav programs use the same API that E911 uses for location info
So far, no data connections have been made.
3. Therefore, the only time data would be needed is while downloading map tiles or traffic info (and possibly other reasons: wikimapia, FON, WarDriving, or NAC Geo services... to name a few)
4. What this all means is that if you store map tiles on a storage device and have a Nav Prog that accesses the same API as the E911 service (which it has to in order to find your location) then there is no use of data.
5. WinMo Programs such as TomTom, IGuidance, Garmin, IGo, OnCourseNavigator, and CoPilot Live, to name a few, all use stored maps.

Again, let me remind you that E911 Location info has been accessible from any phone with any type of A-GPS since '02 without any service plan... and also that Nav progs use that same location info, consequently not needing data.

If you ever take any graduate level classes that deal with wireless data, you will learn that just because you are not paying for a service plan, does not mean that your phone is not receiving signals from the network. It just means that you can not use those signals for dialing out, unless it's a 911 call. Since the GPS function is designed to use with E911, this location service remains intact at all times, even without a service plan. This is the sole reason that you do not need a data plan to access the location info from the A-GPS device, whether it be from a Nav Program or from my camera phone that records location info.

I hope I've cleared this up for you.

It does matter. Theres 4 of them read it and it's all different. Quote my explanation not the it is not require and I will point U to the link where it was explained.
