Mathieulh and his crew have released their long awaited "free" version of the PS Jailbreak code.
To the dismay of the majority of people waiting for it, though, the team have disabled the ability to install games. If running unsigned homebrew code is your thing, though, grab a Teensy++ USB Development Board or an AT90USBKEY and have fun. Or wait for a "third party" to enable Backup Manager support.
UPDATE: The makers of the "Teensy++" have informed possible buyers, that they have received an "Unusual Higher then Normal Volume of Orders", and currently out-of-stock, but trying to get lead-time down to 3 days! http://www.pjrc.com/store/teensypp.htmlThis is the PSGroove, an open-source reimplementation of the psjailbreak exploit for AT90USB and related microcontrollers.
It should work on:
* …and maybe more.
This software is not intended to enable piracy, and such features have been disabled. This software is intended to allow the execution of unsigned third-party apps and games on the PS3.
UPDATE #2: Hackers have released a patch that will allow PSGroove to work with Backup Manager.
UPDATE #3: Over at PS3News, martenbroadclk has now shared pre-compiled hex codes ready to burn followed shortly by hex codes for all boards, including both the original PSGroove release and CJPC's dev_bdvd patched version.
