Mine (Siphon) showed up in Settings listed directly below Store.

Will GV Mobile work for you ? Free also in Cydia.

I have INspell under my Store icon, i'll uninstall it and see if it comes up


gv mobile works for me, trying to figure out the free calls now
 
I used to use Siphone with my Magic jack phone number.
I could also make free phone calls to anyone in the US and Canada thru
3G/Edge not just thru Wifi.
Then Magicjack caught on to it and shut us all down so no more dialing using your magicjack number without that usb dongle :(
But the program was nice.
 
how do you get it over 3g? i tried to slide the toggle to enable it but still get the "service unavailable" error. then i tried to add it to 3G Unrestrictor, and that end up making siphon crash every time, i can only get it to work on wifi...

go to the network settings and put Siphon over Edge/3g on
 
mine is set to "on", but i get "service unavailable", unless i turn on wifi as well...
