Rapper Lil' Wayne, appearing via a video feed from a Riker's Island jail cell, changed his plea to guilty in an Arizona courtroom. The plea deal with prosecutors could keep the rapper from serving prison time in the state when he's released from his current 8 month sentence in New York in October. The Arizona charges stem from an incident at a US Border Patrol checkpoint near Yuma in January 2008 when DEA agents found cocaine, ecstasy, and a handgun on Lil' Wayne's tour bus. Sentencing for the Arizona charges will take place on June 30th, when Wayne could be ordered to serve as much as 3 years of probation.
