Modders and devs will be happy to "note" that the source code to Ice Cream Sandwich on the Samsung Galaxy Note has been officially released by Samsung. Over the past few months we have seen several leaked ROM builds that allowed the developer community to start creating custom ROMS and mods, but this is obviously not ideal, as these ROMs need to be "reverse engineered" for some of the best custom ROMs and mods to work properly. Now that the full source code is out from Samsung themselves, the going should be much easier.
