man this was a mission for me. a quick search on google will get you the patched files.
however when i flashed the zip (or manually added the files and chmod'd them) rebooting my phone would give me a bootloop. clearing cache helped but seems to ruin my link2sd. after flashing backups and trying it different ways, i found that i was able to clear cache, boot phone enough to log into dropbox, and got my bonus gb from there. restored my backup a final time and am good to go.
hope this helps someone.
