Benchmark and GPS-Test later.
MOD EDIT: FYI, this update is no longer available on Kies, the only way to flash it right now is with Odin (which is rather tricky and risky...not recommended for anyone not already familiar with the process!!!)
ALSO...Flashing without unlocking the phone FIRST can make it EXTREMELY difficult (if not impossible) to unlock afterwards!! Be sure to unlock it BEFORE flashing if you're going to need it unlocked in the long run!!
