These are ten easy steps.

Step 5. It should have told you to rebot your device, if not please do so.
Step 6. Make sure you have an email account of some sort, gmail, hotmail, yahoo, ect.
Step 7. Go onto your computer and login in to your email, then download this certificate

Considering Siri Port doesn't work... Your equation should be modified to:
Anything close to Siri that functions at all > Siri Port :carling:
On another note, I use spire in conjunction with AssistantConnect. My friend has to email me a file every 24 hours that I want to use but hey, Siri works perfectly and responds to everything fine. Any mod that has been released for the legit Siri works perfectly as well. I used Sara before that and it really didn't do enough to even let me keep it installed. Seemed to me that, at least at this point in it's life, Sara isn't worth the hassle of saying the same thing into the mic twelve times for it to finally get what I want not to mention the extremely marginal functionality differences.
Spire > Sara > Siri Port
