How to Install Siri on iphone 4

Question

Can we install Siri in iphone 4, mine is not IP4S.

Answer 1

I take it the siri app (which i did see before but only after apple had launched the integrated siri) was an 'app as opposed to an integral software piece?
I know i am one of millions who are frustrated by this latest move by apple and i am confident that i am going to stop being a loyal apple customer if siri dictation is not brought to older devices soon.
There are much more functional handsets on the market now. Android has it's security issues but these are being addressed and let's not forget Steve Wasniak (Apple Co-Founder and chief Engineer at Apple) was quoted as saying that the Android phones on the Market these days are so much more advanced that iOS; until he then released a press statement saying that he had been misquoted....
I also have been a vocal advocate of their products and i have swayed many people over to apple products but now i am going to refuse to and condemn apple to my friends and family as just another conglomerate multi-billion dollar industry.
Moves like these, together with the passing of apple's founder and figurehead will result in apple - the company that has until recent years always played second fiddle to Microsoft - sliding in one direction, down.
