Hey all so I heard some people on the radio this morning chatting about jailbreaking their iPhones, they seemed to say it helped out a lot but what exactly is it? What are the advantages/disadvantages? If you jailbreak it can you set it back to the regular phone again if you don't like it being jailbroken? I have heard of jailbreaking in the past, but I never paid much attention, but it seems like maybe a good idea. Sorry if this is a bit of a newbie question, but I was just wondering about jailbreaking.
