I have an antique 8Gb I phone (Edge version---assuming all Edge, non-3G, versions are 1G). I recently updated to 3.1 (which may have been a mistake) I want to finally jailbreak. I've googled and searched here but only find help jailbreaking 2G & 3G iphones. Is there a firmware when jailbreaking capabilities for iPhone 1G stopped? Can I jailbreak 3.1 1G iPhone? In my searches I heard a lot about carrier updates, which I installed as well. Did that have something to do with MMS? I still haven't received a pix message so I'm not sure if I have that capability. It seems there's much more to know about iPhones that I for some reason have been missing out on.
