Today we have the PS3 CFW 4.xx + F.A.R (Full Auto Resigner) version 0.5b.  This has been tested and confirmed working by our buddy tbad over at dashhacks.  The changelog for this latest release of PS3 CFW 4.xx + F.A.R is listed below.

Automatically unpacks, resigns, finds/adds "Content and Title ID" to package.conf and repacks .pkg files (Just drag and drop your .pkg file on the "CFW 4.xx+F.A.R. Script (Drag Here).bat")

Automatically detects if the input file is an EBOOT.BIN and is able resign DISC and NPDRM EBOOT.BIN's (Drag and drop the EBOOT.BIN on the .bat and select DISC or NPDRM at the prompt)

Automatically makes a .BAK (backup) of your original EBOOT in it's source folder.
