What's up with 4.0? It's theoretically possible to chainload a 4.0 kernel on top of 3.1.x, which would allow the existing userland exploit to run a jailbroken 4.0 for devices with saved 3.1.x SHSH blobs, but quite hard. Instead, I'm focusing on exploiting a new bug, which is actually easier and should work on the iPhone 4 as well...
