Have cell service thru Verizon. My sons phone suddenly went from 1X service to D. His phone went into DEBUG mode the same day, can't get it to stop. Verizon sent new phone, DEBUG mode started as soon as phone was programmed. It changes his lock code and everything. He doesn't have internet access with it, so it couldn't be a virus. Local Verizon store is clueless. Anybody else had this problem? He has a Samsung Intensity III phone.
