PS: I'm guessing here that the iOS behaviour when it comes to hostnames is similar to Lion's.

Make sure to sync it afterwards
To confirm it kicked in, open Applications -> Utilities -> Terminal and type 'hostname'. This is what anyone else on the same network sees you as. You'll also see your machine on other Macs in Finder under the 'Devices' sidebar.
(the whole story surrounding hostnames is moderately more complicated than this, but the Sharing panel on System Preferences is what informs the Bonjour local network name and that's good enough for 95% of user-facing things)
Edit: I misread, thought you were talking about OSX.
The easiest way to bypass HandsOff/LittleSnitch is by temporarily replacing a trusted executable with another binary - there is no mechanism in place to verify that the binary itself hasn't changed since it was granted permissions.
"You must be <name snatched from her ipod/ipad>?"
"Yes?"
"He's not coming."
Very big security problem, indeed.
Or the creep.
For example:
I am not a playboy. I do not offer personalized dating advice, or comment on the suitability of any individual statement to potential romantic partner. Remember, poor flirting can cause total loss of social credibility and you should always consult with your conscience before flirting or beginning a romantic relationship.
