I'm helping out my friend by jailbreaking her iPhone EDGE. She wants it unlocked as well, so I just have to ask. How do I (step-by-step) jailbreak and activate and iPhone EDGE? From time to time, I hear stuff about modem versions, and how if people updated the modem then the iPhone is "bricked". Can someone explain that to me? And what do I need for the jailbreak? What files do I need?
