A magistrate agreed to push back the trial of David Kernell, the son of a Democratic Tennessee legislator, from May to October.
Kernell allegedly gained access to Palin's account in September by correctly answering a series of personal security questions.
The added counts are fraud, unlawful electronic transmission of material outside Tennessee and attempts to conceal records to impede an FBI investigation.
Both the original and the superseding indictments said Kernell tapped into the Alaska governor's widely publicized Yahoo e-mail account, reset the password and was able to read the contents, make screenshots and post his exploits on the Web using the nickname "rubico." The indictment said at least one other person followed a similar path into Palin's account.
Kernell is the son of longtime state Rep. Mike Kernell of Memphis.
