iPhone OS 3.1 plist reveals new Apple “iProd”?

The recently seeded iPhone OS 3.1 beta contains a particularly interesting plist file. In the “USBDeviceConfiguration.plist” file, lies a previously unseen device: the “iProd1,1.” This new name harkens back to a few months ago, when an “iPhone3,1″ appeared in a plist file. Months later, we were given the now-current iPhone model.
