    i installed siri through spite because i have 5.1, it installed siri and spire so i can enter a proxy address, so i have siri up and saying “i’m really sorry about this …”, i put http://i4sirifree…… for proxy address, went to website got certificate, still no go so i tried to get i4siri through cydia but it wont let me depends on spire and ive read spire doesn’t support 5.1 but i have it, if i have siri, spire, certificate, and proxy, do i need i4siri download. why cant i download i4siri it says jailbroken 5.1 will work, but when i try it depends on spire which i have already so it shouldnt need to download it.

    p.s. i wanted not to update to 5.1 i had 4.2.1 could not get 5.0.1 to work at all tried for three days i tried 3 differnt last lines in the host file, erasing the content, putting number sign in front of it, all that, tinyumbrulla latest version wont run error 16, error 3194 or couldnt connect to iphone update server

  • Steveregs

    and opening remote zip takes like forever for me. I think I’ll wait for the iPhone 5 and buy a factory unlocked one as my iPhone 4 is still on 4.11.08 and no solution after all this while. I’m tired of all these.

  • guest

     Hey Kakaniaz
    isn’t just boot  for tether jailbreak, mine is untether

  • Corey Marshall

    i downloaded spire, set the proxy up and installed the certificate. Everything was working fine. Held the home button and Siri came up and when I said hi Siri, she replied 
    “I’m really sorry about this, but I can’t take any requests right now. Please try again in a little while.”
    I followed everything precisely, so why is it not working.

  • UnlockBoot

    Try install again, and follow Steps in tutorial !

  • UnlockBoot

    Add free i4Siri Proxy !

  • Corey Marshall

    I re installed spire and followed the steps in the tutorial and she still replies “I’m really sorry about this, but I can’t take any requests right now. Please try again in a little while”
    I have an iPod Touch 4G 
    Other websites say you need to delete the assistant.plist file and some don’t 
    Why isn’t it still not working
    Thanks
