WASHINGTON — There is one addiction President Obama will not have to kick: his BlackBerry.

For more than two months, Mr. Obama has been waging a vigorous battle with his handlers to keep his BlackBerry, which like millions of other Americans he has relied upon for years to stay connected with friends and advisers. (And, of course, to get Chicago White Sox scores.)

He won the fight, aides disclosed Thursday, but the privilege of becoming the nation’s first e-mailing president comes with a specific set of rules.

“The president has a BlackBerry through a compromise that allows him to stay in touch with senior staff and a small group of personal friends,” said Robert Gibbs, his spokesman, “in a way that use will be limited and that the security is enhanced to ensure his ability to communicate.”

First, only a select circle of people will have his address, creating a true hierarchy for who makes the cut and who does not.

Second, anyone placed on the A-list to receive his e-mail address must first receive a briefing from the White House counsel’s office.

Third, messages from the president will be designed so they cannot be forwarded.

The battle over whether the president could keep his BlackBerry has been fueled to a large degree by Mr. Obama himself, who mentioned it again and again. He would not take no for an answer. In an interview this month, he worried aloud, “They’re going to pry it out of my hands.”

Mr. Obama received his BlackBerry on Tuesday, but officials declined to specify what kind. In a conversation with reporters on Thursday evening, he said, “I don’t think it’s actually up and running yet.”
