Hackboy
Hackboy is an iPhone/iPod Touch app that can help you hack terminals. It works pretty well, with a 95% chance of being correct.

How to use
You type in all of the words given to you on the terminal (20 in all), this task can be a little tedious, but will probably be correct. VERY USEFUL for very hard terminals.

Other
The app costs $1.99 US. not sure if it is available for anywhere else in the world.
