I'm guessing that you are referring to lines on the display? Have you tried to reset the device? Hold the sleep/wake and home buttons together until you see the Apple logo and then release. When the phone restarts, see if they are still there. Restore is the next step if necessary.

The last user troubleshooting step is a restore. Check this support document http://support.apple.com/kb/HT1414 about restore. Just be advised that a restore will delete content from the phone. If you restore from a backup, then it will put content back on, however if it is necessary for you to restore as a new device, everything will be deleted. Make sure content is synced and backed up.
If that doesn't do it, then make an appointement at the Genius Bar of the Apple store to have the hardware checked. If under warranty and found to be defective, they will replace the device. If no Apple Store close,then contact Apple Care.
