The Cavs (9-3) are a half-game ahead of the Pistons (8-3) in the Central Division.
It looked as if Cleveland was going to beat the Pistons the first time it saw them with Iverson, leading 24-16 after the first quarter and enjoying double-digit leads in the second and third quarters.
But Wallace made two free throws early in the fourth to put the Pistons ahead for the first time since midway through the first quarter.
After some lead changes, Wallace gave Detroit the lead for good with 3-pointers on consecutive possessions midway through the fourth.

Notes: The Cavs put Wally Szczerbiak on the inactive list, excusing him to address a personal matter, and activated Darnell Jackson. Coach Mike Brown said he didn't know when Szczerbiak will return. ... The Central Division rivals don't meet again until Feb. 1 at The Palace before playing Feb. 22 and March 31 in Cleveland. ... Ilgauskas made the seventh 3-pointer of his career and attempted two from beyond the arc in one game for the first time. ... Kid Rock sat in the front row at The Palace, which had numerous patches of empty seats in the upper level in another sign of the Motor City's economic woes.
