Your friend's phone will ring and after they hear a brief 'Jajah is connecting your call' they will be calling you and incur all charges. As an added bonus you will quite probably receive your friend's latest voice-mail message as your own (at least on Irish networks), which you may or may not wish to hear. There is even a Jajah Firefox extension — which at the time of writing is the Firefox featured add-on — so you can do it right from your browser. This is about the best example of a bad idea, with terrible implementation, that I have seen all day. And with the wonderful publicity the Firefox page offers it should reach a wide audience in no time."
