I'm visiting Canada for a few days. I would really love to have the GPS and mapping software usable up there, but for right now I only want to ensure that VZW isn't going to bury me in International Roaming fees. I don't really see a setting for turning off the phone antenna, but Airplane Mode will do that, right? (Menu/Settings/Wireless & networks/) I'm assuming that Airplane mode shuts off the main antenna, WiFi and Bluetooth. I noticed that WiFi can still be turned back on, however, so the DROID can still access the internet when I run across open WiFi points. Are there any other settings I should worry about? Going through WiFi, I can't check my data usage via the My Verizon widget (apparently only works via their network, not WiFi) so I won't know if my phone is running up my bill until after I get back to the states.
