Last week there was a thread about a guy who jailbroke his iPhone, saw Cydia, then didn't know what to do so he restored his phone.
Some people are just uneducated, it seems like it takes one big screw up for people to learn what to do.
It's a shame that for many the learning process still includes one big screwup before they focus on the research. With all the information available to us via the web, this trend should be reversing, but for some strange reason it's not. Boggles the mind!!
