OK, I'll just come right out and say it: I have it on good authority that Motorola and Apple are about to release the first cell phone to run iTunes, marking a massive milestone in the race to sell digital music on the cell phone platform. The announcement could come as early as tonight, at the opening night of the CeBIT conference in Hannover, Germany. The other possibility is that the two partners will spring it on us at the CTIA conference, which starts this Sunday (March 13).
