Jailbreaking among phones have become really common, especially among the Iphone or Itouch owners, due to tons of possibilities that you can do to your phone after doing it. Jailbreaking your iphone/itouch can really be easy due to numerous instructions available over the net regardless if you have Windows or Intel Mac installed in your phone, but of course, everything falls under your discretion and people that do this on their own should understand that there is a slight possibility of breaking the phone itself and not just jailbreaking it.

No matter how you did it, the main thing to do if in case your phones act up is to restore everything through iTunes as they have just the tool for such thing. If successful, everything should be fine and your life becomes a lot easier, but still, just be cautious with this because iPhones and iTouch are not exactly the cheapest gadgets around.
