Yeah. I got my iPad after apple stopped signing 4.3.3 so I can't downgrade if I don't like ios5
I think you are spot on there. JB brings to much.
I had to do a restore after Apple stopped signing 5.0 so am on 5.0.1 on my 4s which is nightmare after reading the devs are working on a jailbreak for 5.0 and have said not to update to 5.0.1![]()
I'm pretty sure the jailbreak will work on both 5.0.0 and 5.0.1 since apple is fixing battery life issues and not patching jailbreak holes.
If you have a look under Kernel you will see Apple have patched the hole found by Charlie Miller in 5.0.

Hopefully this isn't the only way to JB IOS 5.
