I feel like I want to become a jailbreaker or a hacker. These names are cool and my mom would be proud of me. Anyway, here are my questions. . What are the reasons for jailbraking an iPhone (I am not too clear about the whole thing) . Is it to use your iPhone on other carriers that ATT? . Isn;t a problem when you bring your iPhone to the store for repair or exchange? Hope to hack soon!
