I have a similar issue.... The touch.facebook.com webiste does not load anything. Just "Loading" and the top headers of the page appear.
I did a factory reset of the phone also. but the the issue is not resolved.
This issue happened all of a sudden. It was opening the previous night. And in the mornign when i open it.. It is not opening.
Have you tried using the integrated facebook application on the phone?
With regards to accessing facebook using your browser, you can try the following troubleshooting steps:
1. Make sure that you have stable internet connection. Try using Wifi if you are currently using 3g.
2. Power cycle: turn off the device. Remove the battery. After a few minutes, turn the battery back and switch on the device.
3. If still the same, try restoring the phone back to its default settings (personal data will not be deleted.
If your phone is not working properly, you can reset some settings to their original values.
End all active calls and connections.
Select > Settings and Phone > Phone management > Factory settings > Restore .
4. If no progress, you can check for updates or reinstall the software using Nokia Suite.
