tai tiekos ir naudos dbr ish ps3jailbreak'o.. piratams belikus viena 
isheitis jei nori naudot ps3jailbreak'a: ne'update'int konsoles i 3.42/3.50 
firmware'a/laukti custom firmware ar kazko pan. ;]

Sony's latest firmware update, 3.50, seems to have disabled a number of 
third party devices. In response to the recent attempt to hack the PS3 via 
USB, this latest move will counter those actions by disabling third party 
USB devices and making the PS3 secure from such hacking methods. Aside from 
USB devices, the new enforcement may also cause problems for some third 
party controllers.
<...>
The controller will only cease to work if it works via USB and if the 
product isn't licensed by Sony -- so some third party controllers should 
still function fine. This is the second time Sony has increased security on 
the PS3 with the recent rise in hack attempts. This seems to be the biggest 
step forward against the attacks and should provide a strong sense of 
security against potential, future attempts. Microsoft did a similar move on 
the Xbox 360.
