Ars Technica is reporting that the latest beta version of iPhone OS 3.1 which was seeded to developers last week contains an updated configuration file that has references to two mysterious products known as “iProd0,1″ and “iProd1,1″.

You might remember that iPhone OS 3.0 had first revealed reference to “iProd0,1″ in the same configuration file along with reference to “iPhone2,1″ which turned out to be iPhone 3GS. However, reference to “iProd1,1″ seems to be a new addition.

Ars Technica explains:

The iProd1,1 device has been assigned a new productID of 4762 (versus 4757 of iProd0,1) and assigned a different ConfigurationDescriptor of “standardMuxPTPEthernet.” iPhone models also have this designation, and the additional interface identified in the plist for this configuration is “AppleUSBEthernet.” The consensus here seems to be that the new device may have gained high-speed networking capabilities — though the iPhone uses the interface to tether to a laptop to share its 3G connection.

MacRumors points out that:

The numerical designation on “iProd0,1″ suggested that the device was simply a prototype, but the new addition of a “1,1″ version of the device implies that it may now be approaching a public release.

It is speculated that “iProd” stands for Apple’s rumored tablet computer. However, other possibilities include:

• the next generation iPod Nano which is rumored to have a camera, but it is unlikely to be based on iPhone OS.

• the rumored iPhone Nano but Apple had categorically stated that they are “not going to play in the low-end voice phone business.”

They also think that a 1,1 moniker suggests that the product will be released soon and perhaps as early as September when Apple is expected to release the next generation iPods.

As you can see above, there are also references to unreleased products “iPhone3,1″, “iPod2,2″ and “iPod3,1″ in the configuration file which could be next generation iPhone and iPods being tested.
