...TMO Samsung Highlight? I have a Samsung highlight under Tmobile and I currently use the unlimited Talk and text plan. I don't use the web often but what I found I would need now and then is Google Maps or some kind of GPS. With the plan I am using the only data plan I have available is a 'Web Daypass' if I used this and downloaded Google maps would I need a data plan to use it or would I have to use the pass every time I needed it. If I would need the pass are there possibly any alternatives that don't require a data plan to use once downloaded?
