As of Jan 2013, is Siri available on the iPhone 4?

The most recent info I can find on this is that Siri is only available on iPhone 4 through jailbreak, but once done, you can't get to the Apple server. So no to Siri on iPhone 4. But all posts are a year or more old. Any positive updates here?

No unfortunately not. The apple website still states siri on 4s and 5.

No, it's only available on 4s and 5

  • Why is IPhone Siri funnier than iPad Siri? I have an iPad mini. Siri is so boring on mine. She just says, "I can't answer that." Or "is that so?". On my friends iPhone, she replies really funny. Also on the Internet I see funny convos with Siri all from iPhone and not on iPad mini. Why is it that siri is funnier on iPhone? They are both part of apple!
