It is .support.plist
It's a hidden/invisible file because of the '.'
In iFile's Preferences, enable 'Hidden Files', and you'll see the file.
Ahh there we go! Thank you so much. I just deleted it.

Lol, I got the 4s because of the hardware, not Siri (which is useless in my opinion)..well I wont say useless, I mainly use Siri to ask stupid questions to see what responses I get and setup reminders etc. If I had an iPhone 4 I def wouldn't pay 20 bucks and go through the trouble of setting it up. But that's just me lol
To me, it was definitely worth it to pay the $20. Siri is one of those things that you have to get into the habit of using. I actually use all the time. Reminders, to tell me when my next work shift is, to check stocks. And the siri tweaks in cydia make it 100x more useful.
