Hi I need help with my hero. My phone was almost dead today so I just turned it off. When I got home and plugged it in and turned it back on I didn't have any service. It says no service. I have turned it on and off several times and have taken the battery out and put it back several times and nothing works. I have only had the phone for approximately 3 days. Anything I can do to fix it myself? I can't even pull up the phone pad or certain settings because I get an error message. I called technical support but because I can't get to the phone pad they can't help me.
