I'm traveling in Taiwan and have a weird icon on my status bar that's not listed on http://www.droidforums.net/forum/droid-faq/745-droid-phone-status-notifications.html. The left side has a white exclamation point in a black triangle but when I try to look at the message, the preview says something about data roaming but when I tap the message, the status screen closes right away. I don't know what that's about but I don't care so much because I don't want to do data roaming. But on the right I have a hollow black triangle that I can't find any explanation of. Then four bars of cell connection and the batter indicator. And I don't get a WiFi indicator, even when connected. What's the hollow black triangle?
