"A person known as NTAuthority has successfully ported psfreedom to the Iphone. Currently it does not feature backup manager support, and currently can not be patched in. However, NTAuthority is investigating this issue and working on a fix. He is referring to this release as a preview (beta) release, so if you are an enduser you may want to hold off until the code is a bit more final. For those planning on testing it, it will work on the iPhone 2G/3G and iPod touch 1G and needs OpeniBoot installed."
