Is the whole point of jailbreaking to run cracked applications and warez? Or to change themes or something? I have never owned an IPod Touch so I don't know its limitations but want to buy one for Christmas. I don't understand the big picture here... are there freeware apps or something that are impossible to install without jailbreaking? Or is this all about warez? Can someone please help an old guy understand what the excitement over jailbreaking is all about??
