PlayStation Jailbreak was the first Universal Serial Bus chipset that allows unauthorized code execution, such as homebrew, on the PlayStation 3. It bypasses a system security check using a memory exploit which occurs with USB devices that allows the execution of unsigned code. One of the most popular pieces of homebrew software used with the device is Backup Manager, which allows users to copy game titles from the optical media to the hard drive of the PlayStation 3. Backup Manager can also be used to run homebrew applications that are created to run in the console's native mode.

Multiple devices to perform code execution exist, such as the open sourced versions (e.g. PSgroove, PSfreedom). Most of these only work on PlayStation 3 system software v3.41 or lower as PlayStation’s System Software v3.42 patches the mod chip exploit on the console. The creators of PS3 Jailbreak also released PSDowngrade which enables downgrading of PlayStation 3's System Software to v3.41 (Or lower) from v3.42, v3.50, and v3.55.
Present and future support
In August, 2011, information about hardware that was downgrading PlayStations on system software v3.70 was being released. These hardware mods were Nand/Nor chip flashers that would either be soldered or clipped onto the PlayStation’s chips on Nand/Nor chip located on the PlayStation’s motherboard. It would then flash the memory off the chip and backup the PlayStation's firmware hence downgrading the console when the hard-drive was formatted. These flashers still work on the latest system software version and can be purchased online.
In October, 2012, a hacking group known as The Three Musketeers released the Level 0 keys for the PlayStation 3. These were the same keys that would have allowed a Chinese hacking group known as "BlueDisk" to release a purchasable CFW (custom firmware) for 4.21 and above. Shortly after, a well-known PlayStation 3 developer, "Rogero," released his free of charge 4.21 CFW. There are now different developers releasing CFWs for the latest versions of PlayStation 3's firmware. These custom firmware render the PlayStation Jailbreak obsolete. They cannot, however, be installed unless the PlayStation 3 is on system software version 3.55 or below.
On June 26, 2013, the 3.60+ loader keys were released to the public by "The Great Unicorns" and on the same day hard-drive encryption for PHAT consoles were released by a developer called "flatz." Following this the Lv1ldr crypto keys were released for 4.21-4.46.
Legality
Sony, after questionable collection of IP addresses and personal information of users even just viewing any of Hotz's sites, Twitter, Facebook, etc., reached settlement with Hotz out of court.
