I just recently bought a iPhone 4 from AT&T, and I want to JailBreak it. I'm using the latest build of greenpois0n, and I'm following all the steps correctly. But when I start up greenpois0n it has two CMD windows saying "Error The process iTunes.exe could not be found", and the same thing pops up for iTunes helper.exe. greenpois0n still works, but it stops when I press the Jailbreak button. The loading bar never loads. Any help? I've reinstalled iTunes, and I've restored my iPhone 5 times now. -_- Thanks.
