There are an increasing number of jailbroken applications that can be loaded onto the iPhone — so many, in fact, that someone has thrown together a nifty package manager for installing and managing all of them.
One of the more interesting things to do, of course, is run an SSH client so you can perform remote administration of other machines. Apparently, the installation of SSH from the package manager is a full-fledged OpenSSL install — including the server side of things.
And yes, it does start up the SSH service.
Combine this with the well-known passwords for both “root” and “mobile” accounts and what do you get?

Hmm… methinks the potential for havoc may be high here.
