I read an article on HN about a jailbreak coming out for iOS 5, so I decided to give jailbreaking a shot. I jailbroke my 4th generation iPod touch. I have looked around Cydia a bit, but have not downloaded anything yet. I am not very knowledgable when it comes to jailbreaking, but I am sure there are some HN users who are. Please share your opinion on the best things you have gotten from Cydia, so I can make the most of my jailbroken iPod Touch.
