I just signed up for the iOS dev program a few days ago, as I'm taking college courses for iOS development. I'm waiting for my activation to go through, so meanwhile I was wondering how many things I can add to my account for beta testing iOS? I have an iPhone, a Gen 3 iPod and a Gen 4 and an iPad2. Will I be able to get iOS 5 beta on all of those or do I get to pick just one?
