It's only been about a month since the last leak, and already we've got another, bringing the build up to I9100XXLPB. So what's new? This build is big on performance improvements. Those who have spent time using it specifically cite better battery life, faster animations, and general speed. It's not all performance though, they have also added in a 3D effect for homescreen transitions, likely derived straight from ICS. The consensus is its ready to be a daily driver as well. So, if you think you're ready to update then simply apply it through Odin or custom recovery. You can get the leak from SamMobile by clicking on the source link but you have to register as a member in order to download. Otherwise, its likely the build is elsewhere online just remember you're looking for I9100XXLPB.

Great, Does the installation via Odin will wipe the phone ?
Yes, that will wipe it. In all my times using Odin I’ve never tried to not wipe.. Flashing it through custom recovery would allow you to update without wiping but ultimately a clean install is usually the best install anyway.
