Last week, I guessed that iOS 7.1 would be shipping this week, but then Mike Beasley poured cold water on that assumption. But today, John Gruber wrote this little nugget:
I’ve heard from a little birdie that the [iTunes Festival] app requires iOS 7.1 (which explains why the app isn’t out yet). That means iOS 7.1 should ship any day now.
I guess I have a rough deadline now.
