I have paid $99 and have a developer account. I have iOS 7 loaded onto my iPhone 5. I want to install it onto my iPhone 4S for testing. I cannot for the life of me figure out how to do this. How do I do this? I know you can add up to like 100 devices or something. Do I just hit add device and pop in the UDID? And then connect the 4s to my mac and load ios7? Or do I need to register the 2nd udid or something? To get it out of the way: Um, if you are a developer you should know how to do this. Non-developers should not be loading betas onto their device because us "real" developers are vastly superior to other humans. This is why non-developers shouldn't try betas. I paid my $99 which is more than a lot have done. I just want iOS 7 on my 2 iPhones.
