This is a firmware update leaked by Samsung. It will be stock, no root, no CW Recovery. All carrier bloatware will be in place.
Assuming this works the same as the I897 leaks, you'll need Odin to install it.
Przekret is great posting the newest "official" leaks so when you see him posting ROMs it's safe to assume it'll be a stock leak. He has been great in providing leaks for the I897 devs and us ROM flashaholics.
