Don’t download iOS 7 today. You’re not a developer. If you were a developer, you’d already know how to download Apple’s newest mobile OS and you’d be making bank by building apps.
But you? You’re just some Apple fan who thinks they need the new juice before it comes out to the general public on September 18. Downloading it before then will probably just brick your phone. Sure, you’re going to buy the next model immediately anyway, but you’ll need to keep this one functioning until then.
Chill out. Visualize all the pretty new iPhone 5C colors. Doesn’t that feel better?
