Okay, so I updated my iPhone 3G to 4.0.1 and it got restored. I followed a tutorial and downloaded redsn0w 0.9.5 but my mac (OS X 10.4.11) refuses to open it. I tried downloading earlier versions of it (0.7.2) and those I can open but it doesn't recognize both 4.0 and 4.0.1 ipsw files. According to the application info 0.9.5 is intel based, not universal, so maybe that's why? If so, is it possible for me to find a universal based version of it? Or will I have to do this on a windows computer?
