As I posted elsewhere, I am moving back to vzw from tmobile. I am torn between getting an N1 (when it becomes available) and a storm2. I really like the garmin GPS (I have one of their dashmount units), but I could replace it with the new phone, if need be. One reason I was tempted by the storm2 is the touch-screen interface to the GPS app. Which leads me to my question: if I had a non-touchscreen unit (bold or tour2), how does the GPS app work? I assume you have to use the menu somehow? Seems less convenient?
What you might miss on a Tour compared to a touchscreen device is the larger display of the touchscreen. The menus are easy to navigate, and typing addresses on a keyboard is easy, but the trade-off is a smaller screen, unless you get a device that has both a touchscreen and a keyboard.
USCellular users seem to have many problems with GPS. USCellular does not disable it, so it should work, but often doesn't. I recommend you try the free trial to see how well it works before you spend any money.
