Where the repair and modding know-how lives. Our own repair guide mirror covers the iFixit guides. For modchips, recaps, RGB mods, region mods and everything else, these are the sites and forums the scene uses. We only link to them: their guides belong to their authors. If you write up a mod yourself, send it to us and it goes on the FTP too.
