I've got my own Siri Proxy running on an Ubuntu Web Server and all tested with my brother's iPhone 4S and my own iPhone 4. I have 2 questions about the setup: 1. Is there any chance the devices could get blacklisted at all? Can Apple notice requests coming at the same time from 2 or more different devices? (In this case an iPhone 4S, an iPhone 4 and potentially an iPhone 3GS) 2. Spire and the Siri Proxy are working fine over WiFi at home but it's pointless when on 3G. Is there any way of getting Spire to work over 3G. I went through the tutorial again on iDownloadBlog and replaced all the internal IP address references for guzzoni.apple.com to my external IP address. However, Siri won't work at all until I switch it back to internal. Do I need to forward ports or something or another?
