not sure what i did but the n1 locked hard when i answered a phone call. I could hear the caller but she couldn't hear me. no buttons would respond and she finally hung up but the phone sat with the same screen. I let it sit about 20 minutes before i pulled the battery and rebooted. Also noticed that my bluetooth calls are sounding muffled... tried several devices including a jawbone2 to no avail. The callers tell me to speak up and i find i'm speaking louder than a normal conversation just to be heard. anyone else seeing these issues?
