I just jailbroke my iPhone 4 and I have no idea where to start. What tweaks, hacks and apps should I install? Is there a guide somewhere? How do I do those cool home screen changes people are doing (without spending money)? P.S: I do not want to pay more than .99 cents for any cydia app or tweak unless it's REALLY REALLY useful. Free is even better. Thanks so much for your help.
