I have very limited knowledge of HTML and CSS, but that's it. I am VERY comfortable with the computer. I have heard a lot of people say to learn C before Objective-C, but I found this super highly rated book by Big Nerd Ranch that teaches you just enough C to understand Objective-C. I want to know if 6 months is enough time to become proficient enough in Objective-C to start iOS development and hacking. Basically, is 6 months enough time to go from here: http://www.amazon.com/Objective-C-P...6285/ref=sr_1_2?ie=UTF8&qid=1322632459&sr=8-2 to here: http://www.amazon.com/iOS-Hackers-Handbook-Charles-Miller/dp/1118204123/ I don't want to be the guy following the tutorials on jailbreaking iPhones, I want to be the one helping write them. What do you guys think?
