If I remeber, several iPhones registered to the BS-11 during
25C3. So it should work (however I cannot test it here, but
feel free to send my an iPhone for playing ;-)

Do you see the test network with the iPhone or does the
registration not work ?

Have you tried to use the SIM card from a phone which has
already registered to the test network ? This way the iPhone
would look at the BS-11 first before trying to search for other
netwoks.

Best regards,
  Dieter
