David Kernell, the son of a Democratic Tennessee legislator, pleaded not guilty to all charges on Monday, and a magistrate agreed to push back his trial from May to October.
Kernell allegedly gained access to Palin's account in September by correctly answering a series of personal security questions, then reset the password, read the contents and posted his exploits on the Internet.
The new counts are fraud, unlawful electronic transmission of material outside Tennessee and attempts to conceal records to impede an FBI investigation.
