Apple is supposedly testing new iPad, iPod, and an "unknown" product using the latest version of the iOS 4.1 beta.

Although the iOS 4.1 beta, now in its third revision, has been available to developers for some time, Appleinsider is reporting that Apple is now using it to test products expected to launch in the next couple of weeks.

The site has found that three new Configuration Descriptors within its USB configuration files, all of which pertain to devices that list Apple, Inc. as their manufacturer, have turned up.

The article goes on to detail those Configuration Descriptors, clearly citing them as a new iPod, a new iPad, and a third device that isn't known, possibly an Apple TV (or Apple iTV) running iOS 4.

iPod 4,1 in the documentation is likely to refer to the latest iPod touch, while iProd 2,1 if following last year's reference of iProd 1,1 is expected to be for a new iPad.

However, a third mysterious device listed only as "unknownHardware" with an Apple product ID of 20547 is also present.
