iPhone Help with restoring iOS 7 iCloud backup would be much appriciated

[Maccyx]

Hi everyone, this is my first ever post as I'm completely stumped as to what to do, I updated my iPhone 5 to iOS 7 beta 1 not long ago from iOS 6.1.4 using the 'check for update' method in iTunes and selecting the ipsw, which worked great. However yesterday I decided to update it to beta 2 using the same method but as it was updating I knocked the cable out and it went into recovery mode. I restored it to 6.1.4 then updated it to beta 2 but now I can't access my iOS 7 iCloud backup up as it says my UDID is not part of the developer program, does this mean that I can never access my back up until the public release? Any help would be greatly appreciated as that backup has everything on it and now I can't assess it or restore it to an iOS 6 device, thanks! 🙂
