I have the iPad 1, and I'd like to use Voice Control on it. However, I can't seem to bring it up the normal way (holding down the home button). Does the iPad 1 have Voice Control?
The only devices with Voice Control of any form, whether pre-iOS 5 "Voice Command" or iOS 5+ "Siri", is an iPhone 3GS or later, and the 4th Generation iPod touch.
All iPhones since the 3GS and iOS 3 (IIRC) have Voice Command. iPhone 4/4S' on iOS 5 or later have Siri, unless disabled then Voice Command is used instead.
iPod touches do not have Siri, though the fourth generation does have Voice Command. No iPad has Voice Command nor Siri. This is true of all models and iOS versions as of this writing.
