I Have a iPhone 3G and have Siri but I don't think iPhone 4,4s, or 5 have it sorry
It is both software and hardware. 1. The software side is the iPhone Side. a. Siri is installed onto the iPhone at the Apple Manufacturing Plant and is then shipped out to you. b. The iPhone and the Siri servers communicate over the iPhone's 3G network 2. The hardware side are the Siri Servers. a. Apple runs and upkeeps servers at some location which provide responses to the iPhone and allow you to use Siri. b. The servers and Siri communicate over the iPhone's 3G network. So the answer is both.
