9to5mac reported that t. Louis developer @plamoni has figured out how to run a proxy server on his computer to fool Siri into thinking it is talking to Apples servers. A demonstration of a proxy for Siri can be seen above. “It allows me to control my thermostat when I am at home. Does not require a jailbreak or anything, since it is all going on off the device.”
The proxy server acts as a middleman that intercepts Siri commands and returns answers. According to the project page, “the idea is to allow for the creation of custom handlers for different actions”. It works by setting up a DNS server on your network to forward requests for guzzoni.apple.com (the Siri servers) to the computer running the proxy.
