A couple days ago we told you about the European LTE Samsung Galaxy S3 (Galaxy S III) being launched with Jelly Bean, and today Samsung has released the kernel source for it. The GT I9305 is the quad-core Exynos version with on-board LTE that we've already seen in the far east, which should be getting its own Jelly Bean update next month.
Like we always say, this code won't be very helpful to the average user. Its value to the fellows building custom ROMs for the US LTE versions of the SGS3 is also a bit up in the air, as the hardware is quite different. Right now, we just need to wait and see what the community can do with it.
