I don't currently have a data plan. Since I'm on WiFi 95% of the time, I don't plan on getting one. The only thing I haven't been able to do easily (without a data plan) is use Google Maps while driving/walking. If I load the maps before leaving a WiFi hotspot, my location is tracked and I can pan around the map. Of course, as soon as I want to view another uncached portion of the map, I can't. Maps are small, and it would be perfect if I could cache maps for a certain area - say everything within 100 mi of my house. Any ideas? Thanks!
