So if you have good programs you don't need data access. Thats why the garmin/tomtom apps for iphone cost so much - they include a full download of maps and don't require a 3g data connection. But if you just want a long/lat read out there are many free apps around.

My missus wasn't using maps services, just trying to record Lat/Long's into a trip journal app, nothing more. My Blackberry's GPS worked without any problems at all. I just grabbed all the locations and e-mailed them to myself (held in the outbox until I could get a cell signal several days later) and presto... then I had to manually enter the coords into a textfile for uploading into her journal on the iPhone.
Anyhoo, hopefully the 4 is more "Magical" and allows the GPS to work regardless of whether Location Service is on or off, or with flight mode.
I wasn't aware that TomTom had an app for the iPhone, I'll go check it out.
