Because there is a good new, now we have a good people, WouterDS using his own hard-earned money to set a dedicated Siri proxy server for anyone to use!
Remember on Spire GUI? Yes the unchangeable requirement to use that Cydia, you must have a Siri proxy to connect to Apple server. But of course that's another problem, since having the proxy one has to own an iPhone 4s in his hand, if that's so why would we need a Spire?
Back to this good people, they have set a site namely The Three Little Pigs, and inviting anyone to use their server for free, however they are also expecting donation. Of course and it's understandable as it's not cheap to handle thousands or might be more request, that would need a solid dedicated server, that's expensive.
So the donations from you will go to pay the hosting costs and keep the site maintained.
