SIRI for iPAD 3 or iPAD 2S

Apple has released iOS 5.1 beta 3 for developers. As usual, developers digging in every new iOS release to discover any secrets or hints at the future of iOS devices. Today, the guys over 9to5mac discovered something potentially major, they found Siri Dictation references for iPad.

Dictation is not actually functional on the iPad 2 running iOS 5.1 beta 3, so perhaps this will be an iOS 5.1 launch feature for the iPad, or it may be an iPad 2S-exclusive feature; a similar process to the iPhone 4S exclusively gaining Siri and Siri Dictation support in iOS 5.0.
