Developers, get ready - Samsung has begun unleashing a barrage of Galaxy S4 kernel source on its open source repository, starting with unlocked editions of the phone and a variant bound for Virgin Mobile Canada.




The distinction between the GT-I9500 and the 9505, in case you're not aware, is one of chipset. The 9500 is the Exynos Octa-powered edition of the Galaxy S4, which has not yet had any official release date attached to it. The 9505 is the Qualcomm Snapdragon 600 variant that will be going on sale in many major markets at the end of this month. The SGH-I337M is the Virgin Mobile Canada version.

For those of us in the US, none of these things really help - all the carrier-branded versions of the S4 in America will have their own, separate kernel source releases, as all will run slightly different software builds. It's likely kernel source releases for those devices will happen in the coming weeks (or months, *cough* Verizon *cough*).
