Apple Computer Inc. said July 7, 2004 said its iPod mini digital music player would be available internationally, beginning July 24, at a price of $249. In March, the company said it would delay the international launch of the player due to stronger-than-expected U.S. demand and tight supplies of the hard drive, which is at the core of the player.
