iPhone screen not working on certain areas

[placebo]

Hi.. iPhone working great until 1.1.1 came along, I can't use the middle line of keys on texting or the bottom buttons on the calculator. Is this some bug from the newest upgrade or do I need to bring it in?

Try restoring.
If it persists take it to Apple.
