Try the usual steps: restart, reset, restore.
If you try restoring from a backup and that doesn't fix the problem, try restoring to factory settings and synching your apps. You'll lose the app data and settings, but if the problem is due to a corrupt cache or settings file, that should cure it. If that still fails to correct the problem, take or send the iPhone to Etisalat for replacement.
