Is my phone ruined?

[johnnyg31087]

Hey, I just got an xv6900 and have made a few minor reg edits but decided to do a hard reset hoping to fix the glitches I was experiencing. Now after the hard reset it started going through a "customization" cab I think and now there is a triangle in the top info bar on the home screen. I cannot make a phone call or send a text. when I try to make a phone call I get a message about how verizon does not recognize my phone. I have tried reseting it a few times and tried programing it which got rid of the triangle but did not solve the problem. Am I screwed or is there a quick fix? Please help...THANKS
