(Sorry for the bad title :-))

I'm a big Android fan. Because of it's open character and if I rooted my Android device, it is even better!
But, unlike many others I am not an Apple iPhone/iPad hater. I think it also kick ass. The Apple devices have more of fun-factor than most Android devices. And if you Jailbreak it, it opens some more possibilities. I will not discuss them here. Also I will discuss how to Jailbreak your Apple iP* device. If you install an SSH server on your Jailbroken device, there are some nice directories on the device. 
Here they are:
