Most common unbearable bug with iPhone 4/4s iOS 7 is the "lag" when trying to text or type in general.
If you're still having this problem - do this.
Go to settings
Click on iCloud
Click on documents and data
Toggle this option off (if on)
If option is already off, toggle it on then back off.
I figured this out and it worked for my fiancé and I's 4's.
Hope it helps someone!
Why do you still have an Iphone 4?
