Hi! When the iOS 7 BETA 1 released, i installed it without any problem. Now i wanted to do the same thing with BETA 2, but there was an error message about the developer program - as i expected, but i also hoped that it's not gonna be necessary as i don't have a registered UDID and as i said, i installed the first beta without it, so i don't understand, whatever. So ok, i thought who the heck cares, let's downgrade to BETA 1, i'm gonna wait for the full version with it. I have the firmware file of course, but now every time i connect to iTunes, it's locked, i cannot reach the usual iPod settings or basically anything else for that matter. Do i have a nice, 32GB brick now?
