An XDA Dev member known as "t4tav" has reportedly coded a sweet PS3 jailbreak that can be executed via a rooted Nexus One or HTC Desire.
However, as Greg of PS3-Hacks notes, a universal Android PS3 jailbreak hack could very well be made available in the near future.
"You should also know that the flashable zips - PS3-signed.zip & PS3-No-More-signed.zip - are packaged in such a manner where an unlocked bootloader is not necessary. [Nevertheless], you still need root," he explained.
"[Anyway], I just cracked open a virgin PS3, updated it to 3.41, and ripped [my own] game...It [was] small and quick to rip and it loads/plays no problem. Again, mad respect to everyone involved with this righteous PS3 hack."
Well, then read on and remember, jailbreaking will void the warranty of both devices - so proceed at your own risk.
