So I joined Apples beta program when OSX mavericks beta came out, I had an old Iphone 4 at the time. I now have an iPhone 6, with iOS 8.3 installed. I've tried updating both through itunes and OTA, but it just says I have the newest version(8.3). I am looking to try out 8.4 beta, but nothing ever shows up!, I have tried unenrolling/enrolling again on beta.apple.com and leaving and joining the beta again, both on the mac and the phone, but still no luck. Am I missing something? I am looking for the PUBLIC betas, I know iOS 9 beta is still developer program only, but I should be able to get 8.4 public beta, right?
