I've had my HTC Hero for one week. First day I got it, I walked into a Radio Shack and connected to the open WiFi instantly no problem. I can connect to any secured network (w/ pwd) no problem. However, ever since I put the phone in airplane mode while on a flight, I haven't been able to connect to any open Wifi network. The Hero detects the network and says I'm connected, but I can't get on the internet at all. The phone says it's not in airplane mode but maybe it still is? help please. I'm running android 2.1.
