As Samsung prepares to release its new flagship to the masses, the company is already making moves to accommodate its open source following. Today, the Korean electronics maker served up the kernel source for three versions of the Galaxy S 4. On tap are two unlocked variants of Samsung's next big thing (GT-I9500 and GT-I9505) along with Virgin Mobile Canada's rendition of the handset. Seeing how you've already seen the device stripped down to its unmentionables, why not go the extra mile and take a whack at its software? That is if you know what you're doing.
