Hi! I have a question about my Hero. Has any of you had a problem with the phone not ending a call after tapping "end call", and the phone saying "call ended" Its happened to me several times, where the person I just talked to, calling and saying that they recieved a voicemail from me right after hanging up, and they could hear everything I am saying, even though I have locked the phone and put it in my pocket. This could be a DISASTER!! Is it me doing something wrong, or is it a problem with the Hero? Help!
