can't update iPhone 6S to public beta 9.1 I have a new iPhone 6S and need to upgrade it to the public beta for 9.1 in order to restore my back up from my old iPhone 

I have installed the profile on the device as per their instructions then restarted but every time I go to settings > general > software update I get this error:


  An error occurred while checking for a software update, cancel or try again


Is their another way to install the beta?

Your question being old, I'm guessing you might be interested in iOS 10 now, which you can obtain through a) a paid Developer account, b) invite to Apple's Public Betas, which should be coming soon, or c) an Apple Seed invitation, which you can't ask for.
