Since the PS3 3.56 signing keys were found people have already started PRE-Signing .PKG files for use when/if 3.56 custom firmware has come out ... So yeah I think that 3.56 CFW will be readily available soon ... Well that's all for this thread
Um i think in 3.56 they change the key used to update the console, so if theres another way to install homebrew without CFW it'll work but I'm pretty sure in 3.56 they patched that
