T.I.'s free ... not exactly, but the rapper, who's currently under house arrest while awaiting trial for federal weapons charges, was granted permission on Thursday to attend an Easter Sunday service at the Georgia Dome in Atlanta.

The court clearance allows T.I., whose real name is Clifford Harris, to leave his residence from 8:30 a.m. until 2:00 p.m. for the New Birth Missionary Baptist Church's annual service. He'll be accompanied by a court-approved monitor and one of his attorneys during his first trip away from home.

T.I. was arrested on October 13, when he allegedly tried to purchase machine guns and silencers in a Walgreens parking lot in midtown Atlanta.

The rapper is currently working on music for his new album, dubbed 'Paper Trail.' "I've got about thirty-some tracks done, but I've got like sixteen that I'm in love with and I'm still working," T.I. told Rolling Stone last month.
