SoonR Talk is an AJAX application running on the Opera browser (which has to be installed on the iPhone). It connects to the desktop via the SoonR server, and then SoonR Talk sets up the call.
And how do you get Opera in the iPhone? it's a mystery...
Basicly this is not really skype on the phone running, its only a kind of frontend on the phone.
Real skype will not be possible before the public toolchain it 100% complete.
To antoher post on this thread on Java apps:
