Ok..ima long time loyal blackberry user. but im finally making the jump to iPhone. 1. browsing isn't terribad 2. Apps 3. lag is non existant compared to a BB etc etc... but now i ask Jailbroken... what exactly are the benefits of it and why do people do it? Since it's such an old term everytime i google all i find is ways how to do it, no explanation of why it's beneficial or harmful. So what exactly do you get out of it? is it reversable?
