Here is how to get skyra1n.
be sure you go into your settings-->general--->auto-lock--->never. then you will be good to go
1) You have to be jailbroken
2) once jailbroke "cydia" will be installed. go to the manage tab at the bottom of the phone, then sources, then edit, the add. once you hit add type in this address ---> "http://repo.technetec.com/beta" . one you have that typed in hit add source. then it will refresh
3) once refreshed, go into the source called "rainstone.co" and look for the tweek called "skyra1n" it should be the very last one
4) click on it, then hit install, confirm. once you do that the siri alternative will be installing. it will take about 10-20 min depending on your wifi/3g connection. after that it will say reboot device.
5) once you reboot the device, it should take you threw the apple set up where you want to hit "enable siri" (if this doesnt work just go to settings--->general--->Siri---> Siri (on/off) on---> fill out your info if you want to below.
6) respring again
7) settings--> skyra1n---> then add your server host
8) (maybe not needed depending on the siri server you use) go into safari then get your siri certificate
