Is Yahoo Mail an exchange account?
No. Unless you were issued your phone by you employer, you don't have a sysadmin controlled exchange account.
What OS version are you running? Any "modifications" or jailbroken?
If you can see the Camera icon, it's not likely there are restrictions enabled on the camera function either, but a good idea to check:
Settings > General > Restrictions > Off
Do basic the basic troubleshooting steps described in the User Guide:
1. Turn off and restart phone.
2. Reset phone - press both home and sleep/wake buttons until the Apple logo appears.
3. Restore phone in iTunes using a backup.
4. Restore as a new iPhone.
If 4 doesn't fix it there may be a hardware failure of the camera, requiring evaluation by Apple.
