Developers, start your engines. T-Mobile's version
of the Samsung Galaxy S II was the slowest in the family
to get the official kernel source
. It's here now, though, arriving on Sammy's site a whole four days after the phone's release; this isn't an eternity by any means, but its counterparts had the source available no later than the actual launch date. No matter the reason, make your way to Samsung's official site to dive in and make some magic happen.
