KaKaRoTo , to whom we owe the first port PSFreedom to N900 what triggered the avalanche of ports on other platforms , said on Blog he was currently working porting PSFreedom on other firmwares for the PS3 and more specifically the 1.3 following the acquisition of a PS3 with this version.
He said he had already made good progress in his carriage and he is already able to dump the LV2 . The rest should happen very quickly. Once the port to 1.3 is completed, KaKaRoTo indicates it will examine the implementation of it for firmware 3.10 and 3.15.
