Ok lots have been wondering about #310 since it was filmed this was the only episode of Season 4 that was never announced after it was filmed and there's a reason for that.
TO KEEP THE MYSTERY of the EPISODE Creator Dan Schneider tells ALL that this episode is going to change iCarly as we know it! so thats why being left a mystery! its kinda good that not EVEN the title will tell what the episode is! so get ready but its a HUGE story changer to iCarly.
