Update: A little digging has already revealed a new product ID contained in the update, referencing an "iPad 2,4". There's some speculation that this could be a reference to a tablet with a modem from Sprint built in, but even if that's the case, who knows if it would actually be released prior to the next generation iPad.
Update 2: More leaks! Now 9to5Mac is reporting on a new device, codenamed "J33", which it believes refers to a new model of the Apple TV box. Hit up the link for a few more well-reasoned rumors, we'll let you know if any more details surface.
Update 3: Ok, now we're starting to think someone in Cupertino is just screwing with us. One more time, sleuths have uncovered a reference to the elusive iPhone 5 (aka "iPhone 5,1") in the code, as shown above. Check the third link for more details from 9to5Mac, and prepare for a whole new round of next gen iPhone rumors incoming any minute now.
