PPC6800 Problems

[hd600s]

I have been using the new Mobile 6.1 for the last couple weeks and everything has been going great until today. I went to reply to an sms message and I hit the center button to "select" it and it didn't respond. Thought that was weird said whatever and I used the touch screen and clicked the message and it locked up. Did a soft reset and put the phone in my jacket pocket and went for a break, took it out to make a call and now my phone says HTC No Radio.... Won't boot, nothing...tried to leave the battery out for 20 minutes and nothing.... no radio....I am clueless what did I do wrong
