Sony has just released FW 4.76 for PS3 and it changed nothing in my opinion. It just improved system stability during the use of some Applications! (This is my guess and not an official Statement from Sony but I’m curious if this is going to be true xD). I’m going to keep you updated about the official statement as soon as it’s released.
User Orion posted more detailed information about the new update on psx-place:
The FW 4.76 Lvl2 kernel is the same as in FW 4.75
All the homebrew that is already compatible with FW 4.75 can be also used with FW 4.76, and even the same Cobra patches and Mamba payloads.
For you CFW Users:
Developer Arch released an updated version of his Spoofer.
