Has anyone had problems with IOS.7?

I have a iPhone 4S and I don't want to mess it up if I get ios7.

Just scroll up and down through the questions… Hundereds of people are having problems and many are trying to get rid of ios7… This is a bigger mess than Windows 8… What a riot

WIth nearly half of iOS devices updated to 7 within a couple of days…

There will be no problems on a 4S…

"If you're worried about your older iPhone 4s not performing well with the newer software, I can attest that it's just fine."
