Eric Day took advantage of hacked access to Siri on Sunday through a hack for jailbroken iOS devices. Siri0us (Cydia source link) adds voice dictation similar to that on the iPhone 4S, allowing the same accuracy and continuous dictation as in the official install. It's known to work smoothly on the iPhone 4, although it may take a speed hit on the iPhone 3GS and current iPod touch.
