Something I discovered today while Jailbreaking my iPad on 4.2.1... I started jailbreaking my iPad with redsn0w on windows 7, all went smooth i've done it multiple times, so it wasn't my first rodeo. So I manage to jailbreak the ipad i see the white cydia icon, and safari doesn't work, so of course I start redsn0w once more, attempt to boot tethered, and I see that it reboots the iPad but no PWNApple, so I attempt to start cydia it crashes, obviously it didn't boot tethered. To make a long story short, if your iPad doesn't boot tethered, you've probably downloaded the latest Redsn0w: redsn0w_win_0.9.6rc8 that doesn't work for me, not sure for anyone else. What does work! ---->> redsn0w_win_0.9.6b5 Just thought i'd share..
