I can't download apps ever since I got the iOS 7 on my iPhone 4S.
Any help would be appreciated

Everybody that jumped on the band wagon is having problems… In another 6 months it should all be fixed

Turn your phone off then turn it back on. Worked for me!

I had the same issue. It would ask me to agree the terms, but not give me an agree button. I went on my mac and went into the app store and tried to download something. It took me to the agreement and I was able to agree and start downloading again.

Sign out of your Apple ID under Settings > iTunes music and App Store.
Sign back in, this should prompt to agree to the new terms, after that I was able to download.
