Hackers, who have been busy trying to get the Siri system interface to work on non-iPhone 4S devices, have found some degree of success with almost all members of the current iOS family now that an enterprising pair have grafted Siri onto a current-generation iPod touch, reports Engadget. As with the other hacked versions, however, the trick is only partly successful -- the modified versions can't work with Apple's servers, leaving the program mostly "brainless."
