Hey mike of sac!
I have a website with a couple of suggestions for you. I would suggest trying the steps for "Restart iPhone" first, and if you are still having issues, I would suggest moving on to the "Restore iPhone" section:
Apple - Support - iPhone - iPhone Troubleshooting Assistant

Take care, and thanks for visiting the Apple Support Communities.
