El Team PS3ITA viene de lanzar su Custom Firmware, también, pero para la consolas equipadas con Firmware DEX. En esta actualización, ahora es posible jugar bajo PSN, obtener acceso a SEN, y al fin lanzar tus juegos sin tener que modificar el eboot o convertirlo para que funcione en 3.55.

Este CFW ha sido probado en multitud de consolas, y por un montón de beta testers, no se han encontrado errores. Como siempre, ni el Team PS3ITA ni PSPStation se hacen responsables de un posible brick.
