Q: I'm trying to update my apps, and it won't let me agree to the Terms and Conditions?

Hello helpmeapple15,

Thank you for the details of the issue you are experiencing with Terms and Conditions. 

For an issue like this, I recommend signing out and back into the iTunes Store on your iPhone:

Changing your Apple ID account

Tap Settings > iTunes & App Stores, then tap the Apple ID signed in.

Sign out of the current Apple ID account and then sign in with another account or create a new Apple ID.

The last step states to sign in with another account, but for the situation you described, I recommend just signing in with your same Apple ID.

If the issue persists after signing out and back in, I recommend resetting your iPhone:

Resetting your device

Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
