Jailbreak your PS3 with Maemo
The Australian company OzModChips, who received an injunction against the sale of their PS3-jailbreaking USB keys has, unfortunately, been delivered the death blow by the FOSS PSFreedom driver, which will allow you to use Linux devices with USB to jailbreak your PS3 (it's only been ported to the N900 and Pre so far, though). 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. Engadget has all of the relevant links listed at the end of their article.
