I'm already a developer and started with ios 5. I started fresh back then as I got my first iPhone a week before the first beta was released. It's as simple as downloading the .ipsw and on my windows machine and holding shift and selecting restore, selecting the proper beta .ipsw and going from there right? Obviously making a backup prior to this and restoring from a back up after ios 6 is on the phone right? I'm a little rusty and just needed some guidance. I'm only a developer for the betas FYI lol
