Jailbreaking an iOS device is often not a dead simple process, unless you can show me how to to jailbreak my 4S. I've been waiting for a jailbreak there for quite a while....
Not entirely true. You can jailbreak the iPad 2 using http://jailbreak.me/if you're running iOS 4.3.3. iOS 5 is still unavailable, and I wouldn't expect it to be available until the corresponding iPhone 4S jailbreak is out.
