Hi there, I just randomly started having an issue with my Captivate.. I cant make any calls, if I try an dial out, it says its Dialing out and in about 2 seconds it says Call Ended, like its dropping calls. I tried calling my cell phone from my house and it sounds like the line is busy. I have call waiting and voicemail, so you dont hear the regular dial tone or directly to voice mail as if my phone is off. My reception status bar is showing 3/4. Not sure what happened, since I was sitting in the exact same position about an hour ago with my phone beside me, and I made a call as well as received one. I've tried making about 20 phone calls thus far, but no luck. I tried restarting the phone.. I pulled the battery for about a minute.. Still same issue. I'm running Serendipity if that matters.
