I didn’t read the readme file until I tried to install greenp0ison on my iPad2 iOS5 (from my win PC) and it froze. Now it’s black. When I try to press sleep button (or any other) nothing is happening, and since it’s my 2nd day using some apple device I’m clueless on what should I do to get it work again. What can I do to fix my 32GB iPad that is stuck on black screen while trying to use greenpois0n? Can anyone help me? Thank you.
