Phones are computers. We really should be past the point where someone is impressed that a phone can run $PROGRAM.<p>Well, after our Lords and Masters the Glorious Carriers have been bypassed and the phone is rooted, anyhow. I really loathe how successful they have been at closing the computers-we-call-cell-phones off. Did I mention that we shouldn't be living in a world where running $PROGRAM on a phone is something that impresses people?
Metasploit runs on other phones too. The Nokia N900 for example. The PwnPhone (<a href="http://pwnieexpress.com/products/pwnphone" rel="nofollow">http://pwnieexpress.com/products/pwnphone</a>) is a commercial supported version of packaged tools for the N900 but the tools can be installed separately.
