I registered and paid for an Apple developer account in order to download the betas. However, I have no idea what I am doing. I download the files and then extract them because I am using a dell computer. Once I extract to .ipsw and try to update from itunes I get an error. Do I have to download Xcode in order to do this? I think my UDID is registered at least thats what it says on developer.apple.com. I am so frustrated ready to get a refund if thats possible. I have searched to no end on tutorials on how to update to 7.1 beta with no success. Any help would be greatly appreciated. Thanks!
