You sure can, but right now you cannot with i-applis or MIDP and from the
meager amount I
know about JPhone's API you cannot either.

Yes, Brew has a safety/security problem that makes them require approval.
If they make
the developers jump through hoops then why bother. It does make you wonder
how they
plan on getting many developers to adopt the platform. If KDDI does a good
job with their security
then maybe we might even see it get rolled into the official platform.
Although, I wonder how they are
going to do this without JNI (Java Native Interface) must have included
hooks directly in the KVM...
I am actually looking forward to all of the differences. It gives us a lot
of search space to find out what
works best for the phones. Luckily the APIs are not too big and complex
that getting acquainted becomes a chore.
