T.I.'s upcoming album, "Paper Trail," has changed release dates yet again. The Grand Hustle/Atlantic album was originally due in September, then moved to Aug. 12, then moved back to both Sept. 2 and Sept. 9. It will now arrive Sept. 30, according to the rapper's publicist.

"We're not ready yet," the publicist tells Billboard.biz, adding that the video for the first official single, "Whatever You Like," "is being shot today and we need more time." The clip will be available in roughly two weeks.

"There was a great demand for the product," T.I. told Billboard.biz two months ago about moving the release date up to August. "Once we put out 'No Matter What,' we got so much positive response that we moved up the date."

The Danja Handz-produced "No Matter What" was the promotional single released in late April, and has since reached No. 42 on Billboard's Hot R&B/Hip-Hop Songs tally.

In related news, T.I. has partnered with the Hip-Hop Caucus to form a vote registration initiative, "Get Out the Vote," targeted at young adults aged 18 to 29. The campaign will kick off Monday (July 28) with a press conference in Washington, D.C. T.I. will be the major spokesman, but will be joined by other celebrities and key figures as well.

T.I., whose real name is Clifford Harris, was arrested last October just
hours before he was to be honored at the BET Hip-Hop Awards in Atlanta. The rapper, who had previous convictions, was charged with possession of unregistered machine guns and silencers and possession of firearms by a convicted felon, and was sentenced to one year in prison and at least 1000 hours of community service.
