Should I buy an Apple TV and what's the benefits of I jailbreak it?
Do you mean iPhone?If you Jail Break your iPhone you can do all sort of different cool things. And you can change it back if you like.I chose not to do mine, although I saw some real cool things on an JailBroke phone...
You can't jailbreak it, don't get it, I have one and I can't stop watching Horders on TLC
It's not worth it
