Siri is the hot search on Google now, so what really is Siri.
It’s an application Apple  provided in the newly launched Apple iPhone 4S, it is a voice assistant for iPhone 4S, you can control the iPhone with your voice of course it is still in beta, but the results are great, user’s response has been pretty good. Users are happy with what Siri can do, such that they can’t stop playing with their iPhone + Siri.
Take for example Danny Sullivan, editor SearchEngineLand.com he has been playing with Siri a lot and posting the same on his Google Plus stream here are a few posts he made on his Google Plus account:

So when did this all begin? Wikipedia entry for Siri says

Siri was founded in December 2007 by Dag Kittlaus (CEO), Adam Cheyer (VP Engineering), and Tom Gruber (CTO/VP Design), together with Norman Winarsky from SRI International’s venture group.

Siri lets you send messages, set you calender, make calls it is a natural voice recognition software which can understand natural accent, it can talk back too.
It can search for information when you ask a question to it and then answers back! Like say apple has this example:

So when you ask “Any good burger joints around here?” Siri will reply “I found a number of burger restaurants near you.” Then you can say “Hmm. How about tacos?” Siri remembers that you just asked about restaurants, so it will look for Mexican restaurants in the neighborhood. And Siri is proactive, so it will question you until it finds what you’re looking for.

Siri is such a proactive topic that people who have android based phones are looking for Siri for android, Google recorded “siri android, siri for android, siri 3gs, siri funny” terms to have been in trends.
So you still have your iPhone 4? iPhone 4 might get Siri says this Engadget post Siri ported to an iPhone 4, old phone learns a new trick (Update: Better performance!)
It says “thanks to the efforts of developer Steven Troughton-Smith and the folks at 9to5 Mac” iPhone 4 might get Siri as well.
Current hack is missing the a GPU driver which is keeping iPhone 4S’s Siri performance so smooth, although iPhone 4 doesn’t have dual core processor its successor has but due to efforts of Mr. Steven Troughton-Smith he has vastly improved the performance of Siri on iPhone 4.
