That qualifier at the end is because Apple does their very best to prevent this sort of thing, and any time you see it being done, it means someone is exploiting a security vulnerability which will surely be patched.

Apple just has to issue a patch for the hack, and may have already, given that the project has been dead for 5+ years.

edit: in 2012, it was deemed not a violation of the DMCA to jailbreak a phone. Whoops.

I don't know what the consequences of exploiting a hole in their security implementation or possibly violating their ToS or EULA.

Trying to profit from such an exploit commercially would test the waters by attracting Apple's legal department.
