a specialized USB key. Four days ago open-source software let you roll your own. Today, there's no need for any of that -- you can hack your PS3 with a tethered smartphone. Working closely with the PSGroove team, hacker Kakaroto adapted the same jailbreak to the Nokia N900, and the open-source community lost no time porting it to the Palm Pre as well. If the videos after the break are any indication, both versions work just as well as the original, and you too can get your game on with downloads and detailed instructions at the source links below.
Sadly, the aforementioned Australian importer OzModChips is a casualty of this little story, with all its shipments of the PS Jailbreak dongle seized (and the item subject to injunction) by an Australian court, but we suppose knowing its product has enabled the hardware hacking community thus might somewhat soften the blow.
