It looks like Apple has closed its Fifth Avenue store, quite possibly because it will film a commercial there overnight for the 3G iPhone. That’s what employees are telling passersby, at least.

The store will be closed from 3pm today until 9am tomorrow morning.

The last time the store was closed? Pretty sure that was for the Leopard launch back in October.

Tell all your friends: Apple Store closed, maybe for a commercial, maybe not.

The Drudge Siren is here, so you know there’s something big afoot.
