Frankly, I don't quite get, why you need so-called pwnphone suite for N900. AFAIK, no one seriously interested in pentesting (aka not "just for show") uses it.

Instead, people are using so-called bleeding-edge drivers (bundled with kernel-power) and either software compiled for N900 itself, or, in cae of more exotic needs, Debian packages via Easy Debian (or other chroot).
