Developer beta to public beta

Yes, it shouldn't be a problem.

Just by following the steps on beta.apple.com?

I can't get on to beta.apple.com at the moment (must be getting a lot of traffic)

If you can see the steps maybe you can post them because the site isn't loading for me.

I can get on but it takes a long time to load. Here are the steps: 1. Archive an iOS backup. 2: Download Profile. 3: Upadate your iOS device (iOS devies running iOS 8.1.3 or later will automatically receive the latest public beta software over the air.)

Yes, that should work fine.

Okay I've had some issues with upgrading to beta 3 so I am trying it again and if that doesn't work hopefully the public beta will work.

Remove Developer Beta Profile and put in the Public Beta Profile.
