The top home page is empty. The bottom has all the Icons
What about the page to the right? (swipe the whole page to the left)
If it has really gone completely, and a simple restart does not bring them back then I would Backup data (only), Security Wipe, Restore data. Reinstall purchased apps and email accounts etc.
