Palm wasn't going to sit still over the issue however, and a wrote a letter of protest to the USB Implementers Forum (USB-IF), the non-profit organization that maintains the Universal Serial Bus (USB) specification and promotes the interface. Apple had blocked the Pre from syncing with iTunes by checking the idVendor descriptor when connected.
The Palm letter informed USB-IF of the WebOS update, which would change the Pre's Vendor ID to the same as Apple's in order to regain iTunes support. "Interoperability is central to any standard-setting organization," the letter read, "because, without widespread interoperability, many of the benefits of standardized (as opposed to proprietary) technologies are lost."
Unless USB-IF intervenes in the situation, this cat and mouse game of blocking and regaining Pre-iTunes support with software updates could continue for some time.
