Hi

That's correct!
Each application needs a an individual creators ID

As I wrote a long time ago:

You get valid creator IDs when you join the Palm Developer Network and
register your application.
You may also make up your own ID as a combination of four characters -
as long as it is'nt already assigned to another application on your
device. ( use for instance: Ro07 ).
You shouldn't use 'own' IDs if you plan to give your PRC away - you'll
never know, which IDs are in use on other devices.
