By means of an official letter, the USB Implementers Forum has criticized Palm for using a workaround to sync the Pre with Apple's iTunes software. The letter is in response to an earlier complaint from Palm, which accuses Apple of violating its USB-IF membership agreement by deliberately blocking third-party devices through iTunes updates. The updates exploit USB Vendor ID numbers, according to Palm, in a way that breaks the "letter and spirit" of USB-IF terms.
